Explanation / Answer

We know that Energy, E = hc /

Where

h = plank's constant = 6.625x 10-34 Js

c = speed of light = 3x 108 m/s

= wave length

E = Energy

From the equation , E is inversily proportional to

(a) As energy increases wavelength decreases.

(b) Also as wavelength increases energy decreases.
