Question:

Which of the following statements is false?

Photon has momentum as well as wavelength

Frequency of emitted radiation from a lower wavelength to higher wavelength as the temperature increases

Rydberg constant has unit of energy

Splitting of spectral lines an electrical field is called Stark effect

Solution:

Frequency of emitted radiation shifts from a higher wavelength to lower wavelength as the temperature increases. Frequency of emitted radiation from a lower frequency to higher frequency as the temperature increases. So option (B) is false.
