Q-00019576
What is the angle of refraction when light travels from a medium with a refractive index of 1.5 into a vacuum (refractive index of 1)?
1
The same as incident angle
2
Greater than the incident angle
3
Less than the incident angle
4
Undefined
Answer and Solution
Answer
B. Greater than the incident angle
Solution:
The angle of refraction will be greater than the angle of incidence, as light speeds up when moving to vacuum from a denser medium.
