Question

WHAT IS THE DIMENSIONAL FORMULA FOR RADIATION ENERGY?

Answer 1

if p represents radiation pressure, c represents speed of light and q represents radiation energy striking a unit area per second .then non zero integers x,y & z such thatp^xQ^yc^z is dimension less are

Answer 2

The radiation energy striking a unit area per second is known as is intensity of a wave..

which have dimensional formula of --

MT-3

according to the question when radiation energy strikes the area then pressure creates and we know the dimensional formula of pressure is--

(ML-2T-2)

and area = L2

time = T-1

so, now --

radiation pressure×area/time..

so, ML-2T-2×L2/T1

= ML-3 ANSWER..
