The relationship between energy E, of the radiation with a wavelength 8000 Å and the energy of the radiation with a wavelength 16000 Å is

Options

A. `E_(1) = 6E_(2)`
B. `E_(1) = 2E_(2)`
C. `E_(1) = 4E_(2)`
D. `E_(10 = 1//2E_(2)`

Answer

B

Explanation

`E = hv =(hc)/(lambda)`
`(E_(1))/(E_(2)) =(hc//lambda_(1))/(hc//lambda_(1)) = (lambda_(2))/(lambda_(1)) = (16000 Å)/(8000 Å) = 2`
`:. E_(1) = 2E_(2)`
