Which of the following is false about wavelengths of electromagnetic radiation


Which of the following is false about wavelengths of electromagnetic radiation

a) Radiation with short wavelengths have high energies 

b) Energy does not depend on wavelength 

c) Radiation with long wavelengths have low energies 

d) Energy depends on wavelength

Solutions

Expert Solution

the energy of electromagnetic radiations depends on the wavelength as per the equation

where is the frequency of radiation. frequency is inversely proportional to the wavelength.

then, Energy is also inversely proportional to the wavelength.

so, radiations with shorter wavelength have high energy.
radiations with longer wavelength have low energy.
Hence, it is clear that energy is dependent on wavelength.

hence, answer: OPTION B
