Question

what is the dimensional formula of radiation energy striking a unit area per second

Answer 1

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..

Answer 2

Answer:

Explanation:

we need to use the principle of homogeneity here
