Question
Electromagnetic radiation with maximum wavelength is :
Options
A.ultra-violet
B.radio- wave
C.X-ray
D.infra-red
Solution
thus smaller is the energy , larger is the wavelength.
Among the given radiations, radio-waves are least energtic.
Radiaation UV Radio -waves
λ(cm) 10-6 - 10-5 1 - 102
X-rays IR
≥ 10-6 10-4 to 10-3
