A beam of light is incident on a perfectly smooth body of water. The angle that the REFLECTED ray makes with the normal is: w) greater than x) smaller than y) the same as the angle the incident ray makes with the normal. Answer : ANSWER: Y -- THE SAME AS...
Light is normally incident on a thin soap film and is reflected. If the wavelength of this light is "L" and the index of refraction of the soap film is "N", complete destructive interference will occur for a film thickness of: w) L / 8N x) L / 4N y) L / 2N z) 3L / 4N Answer : ANSWER: Y -- L / 2N ...
In the Compton effect, a photon of wavelength l (read: lambdw) collides with a stationary electron. The wavelength of the emitted photon is: w) longer than l x) shorter than l y) the same as l z) no photon is emitted Answer : ANSWER: W -- LONGER THAN l...
The speed of light in vacuum "C" divided by the Index of Refraction "N" gives the: w) frequency of the light x) speed of the light in the medium y) energy of the light z) wavelength of the light Answer : ANSWER: X -- SPEED OF THE LIGHT IN THE MEDIUM...
