What is the angle of refraction when light passes from a medium with a refractive index of 1.0 into a medium with a refractive index of 1.0 at an angle of incidence of 0 degrees?
0 degrees
30 degrees
45 degrees
90 degrees
ব্যাখ্যা
When the angle of incidence is 0 degrees, the angle of refraction is also 0 degrees.
