Question

Which physical quantity remains unchanged during refraction?

Answer 1

Explanation:

In contrast, refraction is a phenomenon in which a ray of light enters from one optical medium to another. The two quantities that remain the same in the case of reflection are the wavelength of the light and its speed.

Answer 2

Answer: Frequency

Explanation:

• When a light enters from one medium to another medium then refraction takes place.
• The physical quantity which remains unchanged is frequency of light as it depends on the source of light so the source doesn't change and the frequency remains same.
• Hence, the correct answer is frequency.
