What are focal rays, parallel rays, and center rays?
Focal rays are rays of light that pass through the focal point of a lens or mirror. Parallel rays are rays of light that are parallel to the principal axis of a lens or mirror. Center rays are rays of light that pass through the center of a lens or mirror. These three types of rays are used in ray diagrams to determine the location and characteristics of images formed by lenses and mirrors. **
Which rays are they, X-rays or UV rays?
The rays being referred to in this question are most likely X-rays. X-rays have a higher energy and shorter wavelength than UV rays, and are commonly used in medical imaging to see inside the body. UV rays, on the other hand, have a lower energy and longer wavelength, and are known for their effects on skin and eyes, such as causing sunburn and contributing to skin cancer. Therefore, based on the context, it is more likely that the question is referring to X-rays. **

Which camera app is suitable for a drone quadcopter?
The DJI GO 4 app is suitable for a drone quadcopter as it is specifically designed for DJI drones and offers a wide range of features for controlling and capturing footage from the drone. It allows users to control the drone's flight, adjust camera settings, and capture high-quality photos and videos. Additionally, the app provides real-time telemetry data and a live video feed from the drone, making it a comprehensive and reliable option for drone photography and videography. **

What exactly are principal rays, parallel rays, and focal rays?
Principal rays are a set of three specific rays that are used to determine the location and properties of an image formed by a lens or mirror. The first principal ray is drawn parallel to the optical axis and then passes through the focal point on the opposite side of the lens or mirror. The second principal ray passes through the center of the lens or mirror, and the third principal ray passes through the focal point before being refracted parallel to the optical axis. These rays help to determine the size, orientation, and location of the image formed by the optical system. **

What are X-rays and uranium rays?
X-rays are a form of electromagnetic radiation with high energy that can penetrate through soft tissues and are commonly used in medical imaging to visualize the internal structures of the body. Uranium rays, on the other hand, refer to the radioactive emissions from uranium, a naturally occurring radioactive element. These rays can be harmful to living organisms and are used in various applications such as nuclear power generation and in the production of nuclear weapons. Both X-rays and uranium rays have the potential to cause damage to living tissues and should be handled with care. **
-
Are infrared remote control rays harmful to the body?
Infrared remote control rays are not harmful to the body. Infrared rays are a form of non-ionizing radiation, which means they do not have enough energy to cause damage to cells or DNA. Infrared rays are commonly used in remote controls, heating pads, and even in some medical treatments, and they are considered safe for human exposure. However, it is important to note that prolonged exposure to any type of radiation, including infrared rays, should be avoided as a precautionary measure. **
Why are there heat rays, but no cold rays?
Heat rays are a form of electromagnetic radiation that is emitted by hot objects, such as the sun or a fire. Cold rays, on the other hand, do not exist because cold is simply the absence of heat. Heat is a form of energy that can be transferred from one object to another, but cold is not a form of energy that can be transferred in the same way. Therefore, while we can feel the effects of cold as the absence of heat, there are no "cold rays" that can be emitted or transferred. **
Are laptop rays the same as mobile phone rays?
Laptop rays and mobile phone rays are both forms of electromagnetic radiation, but they are not exactly the same. The specific frequencies and intensities of the radiation emitted by laptops and mobile phones can vary, depending on the device and its usage. Both types of devices emit non-ionizing radiation, which is generally considered to be safe at normal levels of exposure. However, it is important to use both laptops and mobile phones in moderation and follow recommended safety guidelines to minimize potential health risks. **

DJI Neo 2 4K Camera Drone 49GB (Drone Only) - GreyThe DJI Neo 2 is a lightweight and highly portable camera drone designed to make aerial photography and hands-free video creation simple and accessible. Weighing approximately 151g, it features a compact design with full-coverage propeller guards, making it convenient to carry and suitable for capturing moments during travel, outdoor activities, sports and everyday adventures. The Neo 2 features a 12MP 1/2-inch CMOS camera sensor with an f/2.2 aperture and a high-performance image processor. It can record detailed 4K video at up to 60fps and supports 4K slow-motion recording at up to 100fps. It also supports 2.7K vertical video, making it suitable for creating content for social media and other vertical platforms. A 2-axis mechanical gimbal helps stabilise footage while flying, producing smoother and more controlled video. The camera system is designed to capture clear footage while the drone automatically tracks subjects, making it possible to create dynamic videos without constantly controlling the aircraft manually. The Neo 2 features advanced FocusTrack capabilities including ActiveTrack, Spotlight and Point of Interest tracking. ActiveTrack provides improved subject tracking and can follow moving subjects at speeds of up to 12m/s in suitable open environments. This makes the drone particularly useful for activities such as running, cycling and other outdoor pursuits. For easy hands-free shooting, the Neo 2 supports SelfieShot, allowing users to capture solo or group footage without needing a separate camera operator. Gesture control and palm takeoff and landing provide additional convenience, allowing compatible operations without a conventional remote controller. Safety is enhanced through omnidirectional obstacle sensing. The drone combines an omnidirectional monocular vision system with forward-facing LiDAR and a downward infrared sensing system to detect obstacles in real time. Integrated propeller guards provide additional protection around the aircraft, making it more approachable for new drone users. The Neo 2 provides up to 19 minutes of flight time and features 49GB of internal storage, giving you plenty of space for capturing extended 4K footage without immediately needing additional storage. DJI states that the internal storage can hold up to 105 minutes of 4K/60fps video under specified conditions. The drone supports DJI O4 video transmission with a transmission range of up to 10km under appropriate conditions. Wi-Fi connectivity can also be used for convenient wireless transfer of captured footage to a compatible smartphone through the DJI Fly app. The DJI Neo 2 can be operated without a remote controller for supported intelligent features, while compatible remote controllers and FPV accessories can provide additional flight and immersive control options. The drone-only package includes the aircraft, one intelligent flight battery, spare propellers, propeller guards, gimbal protector and USB-C to USB-C data cable.203,99 £*Shipping: 0,00 £Secure redirect to the provider
