How does light behave as it enters these mediums?

• continue its path as straight line.
• bends toward the normal
• bends away from the normal
• reflects

Absolute refractive index of any medium is always _______.

• less than 1
• greater than 1
• 1
• 0

The formula to calculate the refractive index is

• n=cv
• n=v/c
• n=c/v
• v=nc

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.
