Question 429: Wave Optics

Question

A ray of light travelling in air have wavelength $$\lambda $$, frequency n, velocity v and intensity $$I$$. If this ray enters into water then these parameters are $$\lambda $$', n', v' and $$I$$' respectively. Which relation is correct from following ?

Accepted Answer

Frequency remains same.

Answer

$$\lambda $$ = $$\lambda $$'

Answer

n = n'

Answer

v = v'

Answer

$$I$$ = $$I$$'.
