Consider the following quantities I The color of the laser I

Consider the following quantities I The color of the laser II. The intensity of the laser III. The spacing between lines in the diffraction grating. IV. The size of the diffraction grating. V. The distance from the grating to the screen On which of the quantities above does the distance from the central bright spot to the first order spot depend? I. only I, III, and IV III and V I, III, and V It depends on all of the quantities. what wave phenomenon is occurring between the central bright spot and the first order bright spot? Diffraction Polarization Refraction Destructive interference Constructive interference If the scientist uses a diffraction grating with 600 lines per mm and laser with a wavelength of 630 nm. what angle will a line from the grating to the second order bright spot make with the line from the grating to the central bright spot? 49degree 4.3degree 2.2degree 22degree

Solution

7)

Correct option is c

8)

Between two consecutive bright spots there will be dark spot which is destructive interference.

Corroption option is D
