What possible phenomenon can happen when light falls on a surface?

Given,n=1.5 and the speed of light in vacuum, c = 3x 108 ms-1. We know that the refractive index is given by the expression n =c/v where c is the...

(i) A stick partly immersed in water appears to be bent at the water surface. (ii) A pool of water appears less deep than it actually is.

If the iron railing on the road side is not painted, a brown rust would form on its surface because the moist air of the atmosphere reacts with iron to...

(c) the force of viscosity of air balances its weight Explanation:  When the raindrop starts falling the force of viscosity of air comes into action. This force is proportional to the velocity....

(c) both particle and wave phenomenon. EXPLANATION:    The photoelectric effect shows it as a particle phenomenon while the interference and diffraction of light shows it as a wave phenomenon. Hence duel...

The illuminance will not change.

The correct answer is (c) 2%

Since, μ= 1.5, Critial angle = sin–1(1/μ) = sin–1 (1/1.5) = 41.8° We know, the maximum attainable deviation in refraction is (90° – 41.8°) = 47.2° So, in this case, total internal...

(a) The photoelectric effect will take place only if  v > v0.

(c) Photoelectric effect will take place only if  λ < λ0.
