reflection occurs because of the change in speed of light as it enters the second medium true or false
Answers
Answer:
True
"A piece of extra information" :-
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.
Refraction happens because the speed of the wave changes. Light travels slower (compared to its speed in air) in a more dense material like glass. The wavelength will also decrease in order to keep the frequency constant. When light passes from air into a block of glass the following is seen.
The incident Ray,the refracted Ray and the normal at the point of incidence all lie in the same plane. The angle of incidence is equal to the angle of refraction. The angle of the sine of incidence to the angle of sine of refraction is equal to a constant.
