Question

when a light
ray enters into glass medium from water at an angle of incidence 0° , what would be the angle of refraction?
@) 90°
b) 45°
c) 0°
d) The ray will not enter at all
​

Answer 1

Answer:

c) 0°

Step-by-step explanation:

There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero. The same happens if the ray of light falls perpendicularly on the surface of water.
