Question

please answer this please​

Answer 1

Answer:

1) The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

2) Field of view (FOV) is the open observable area a person can see through his or her eyes or via an optical device. In the case of optical devices and sensors, FOV describes the angle through which the devices can pick up electromagnetic radiation.

3) i) Dont Know This One Sorry!.

    ii) A virtual image is a reproduction of an object via light that is formed where the light rays cross when projected back from their path beyond a lens or mirror. A virtual image only exists within the brain of the observer, but is said to exist at the perceived point of intersection

4)  

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave propagation relative to the direction of change in speed.
