remain and uneffect is its

a) speed

b) direction of light ray

c) wavelength

d) frequency​

Answer 1

Answer:

Frequency is the characteristic of the source while wavelength is thecharacteristic of the medium. When monochromatic light travels from one medium to another, its speed changes, so its wavelength (λ=c/v) changes but frequency vremains unchanged.

Answer 2

Answer:

speed may be the correct answer

Explanation:

because light is a energy in which speed never changes but direction may change by refraction.
