Answer 2

I will not solve it for you but I will help you out with the formulae and sustitution...

Answer 3

We know that E=Hv( where v is the frequency)

Answer 4

v=c/Lambda

Answer 5

Therefore E= hc/Lambda

Answer 6

We know h= Planck's constsnt = 6.626 × 10-34
c = Speed of light = 2.998 × 108 m/s
and wavelength Lambda= 6.2m

Answer 7

Substitute them to get the answer ...:)
