Arrange the following electromagnetic radiations per quantum in the order of increasing energy :
A : Blue light
B : Yellow light
C : X - ray
D : Radiowave

Options

A. D, B, A, C
B. A, B, D, C
C. C, A, B, D
D. B, A, D, C

Answer

A

Explanation

Quantam energy = hf
`= (hc)/(lambda)` (hc = constant)
`prop (1)/(lambda)`
Arranging in decreasing order of wavelength Radiowaves `gt` Yellow light `gt` Blue light `gt` X - rays
Hence quantam energy
`therefore` Arrange quantum energy in increasing order.
Radiowaves `gt` Yellow light `gt` Blue light `gt` X - rays
`D gt B gt A gt C`.
