Answer 1

Answer :-

(b) Frequency

✰ More to know :-

• What is Refraction?

Ans. Bending of light from one medium to another is known as refraction

• What are the laws of refraction?

Ans. There are three laws of refraction. They are :-

• The incident ray, refracted ray and the normal of the interface of the two medias incidents/ meets on the same line.

• The ratio of sine of angle of incidence ( sini) to the sine of angle of refraction (sinr) is constant, provided the pair of media and the color or the wavelength of the light remains same. This is also known as Snell's Law.

$\bigstar \: \boxed { \red{\sf \: \frac{sin \: i}{sin \: r} = constant}}$
