A diffraction grating with 600 lines/mmlines/mm is illuminated with light of wavelength 510 nmnm. A very wide viewing screen is 4.6 mm behind the grating. Part A What is the distance between the two mm

A.2.95 m

B.7

Explanation:

We are given that

Diffraction grating=600 lines/mm

d=

Wavelength of light,

l=4.6 m

A.We have to find the distance between the two m=1 bright fringes

For first bright fringe, =1

The distance between two m=1 fringes

Hence, the distance between two m=1 fringes=2.95 m

B.For maximum number of fringes,

Substitute the values

Maximum number of bright fringes on the scree=
