The amount of diffraction depends on the wavelength of light, with shorter wavelengths being diffracted at a greater angle than longer ones (in effect, blue and violet<span> light are diffracted at a larger angle than is red light).
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:
Explanation:
1.3 g = 1.3 / 2 = .65 moles of hydrogen .
.65 moles = 6.02 x 10²³ x .65 molecules
Translational kinetic energy of one molecule = 1/2 mc² where c is rms speed = 1/2 x 2 x 1.67 x 10⁻²⁷ x ( 1600 )² = 42752 x 10⁻²⁵ J
Translational kinetic energy of .65 moles = 6.02 x 10²³ x .65 x 42752 x 10⁻²⁵ J
= 1673 J approx .
B ) Total thermal energy and total translational kinetic energy are same so
Thermal energy of gas = 1673 J
C ) Net content of thermal energy = 1673 + 500 - 2000 = 173 J
If c be the rms speed
1/2 x 2 x 1.67 x 10⁻²⁷ x .65 x 6.02 x 10²³ c² = 173
6.534 x 10⁻⁴ c² = 173
c² = 264769
c = 514.56 m /s
