Refraction of light is the phenomenon in which light changes its direction when it passes from one transparent medium to another due to change in its speed.
Refraction occurs because the speed of light is different in different media.
Q1. Refraction of light occurs due to: A) Change in wavelength only B) Change in direction of wind C) Change in speed of light D) Reflection of light Answer: C Q2. When light passes from one medium to another, it: A) Always bends towards normal B) Always bends away from normal C) May or may not bend D) Gets absorbed Answer: C Q3. The bending of light at the boundary of two media is called: A) Reflection B) Diffraction C) Refraction D) Dispersion Answer: C Q4. Angle between refracted ray and normal is called: A) Angle of incidence B) Angle of reflection C) Angle of refraction D) Angle of deviation Answer: C Q5. Refraction takes place when light travels between: A) Same medium B) Two transparent media C) Two opaque media D) Vacuum only Answer: B
Change in direction of light when it passes from one medium to another due to change in speed.
Different speed of light in different media.
Direct MCQs are asked on definition, cause and examples of refraction.
