Question

Light rays bend as they pass from air into

Answer 1

Answer:

4

Explanation:

Refraction is the bending of light when it moves from one medium to another.

In the situation described:

• The average speed of light changes when it goes to another medium. The speed of light in water is less than in air.
• When velocity/speed changes, the index of refraction changes as well. Water's index is greater than in air.
• Since, speed changes, wavelength changes too.
• Only the frequency remains the same. The rates of vibration stays the same.

Correct choice is #4.
