Physics for IGCSE & O level - Rays And Waves (Section 3 - No. 2)
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
توضيح
When the angle of incidence is 0 degrees, the angle of refraction is also 0 degrees.
