Question

2.113
There are two sources of light, e
re two sources of light, each emitting with a power of 100 W. One emits X-rays of wavelength 1 nm
The other visible light of 500 nm. The ratio of number of photons of X-rays to the photons of visible light
and
of the given wavelength is​

Answer 1

Solution:

given P=100w,λ1=1nm,λ2=500nm

n1= number of photons of x-rays

n2= number of photons of visible light

P=n1hcλ1

=n2hcλ2

n1λ1=n2λ2

=1500
