List the types of electromagnetic radiation in order of decreasing energy per photon.

Incomplete question.The Complete question is here

List these types of electromagnetic radiation in order of (i) increasing frequency and (ii) decreasing energy per photon. a. gamma rays, b. radio waves, c. microwaves, d . visible light

(i) (b) ,(c), (d), (a)

(ii) (a), (d), (c), (b)

Explanation:

For Part (i) increasing frequency

The frequency is directly proportional to energy.Therefore the order of increasing frequency is in the same direction as increasing energy

So the order is

(b) ,(c), (d), (a)

For Part (ii) decreasing energy per photon

This should be reverse direction from part (i)

(a), (d), (c), (b)  

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
