Assertion: Mass of moving photon varies inversely as the wavelength.
Reason: Energy of the particle = Mass x (speed of light)2
The correct answer is option 'A', which states that both the assertion and reason are true and the reason explains the assertion.
Explanation:
Photons and their properties:
- Photons are elementary particles that exhibit properties of both particles and waves.
- They are the fundamental units of light and electromagnetic radiation.
- Photons have zero rest mass, meaning they only have mass when they are in motion.
Assertion: Mass of moving photon varies inversely as the wavelength.
- This assertion is true.
- According to the de Broglie hypothesis, any particle with momentum can be associated with a wavelength.
- The wavelength of a photon is inversely proportional to its momentum.
- Since mass is directly proportional to momentum for a photon, the mass of a moving photon is inversely proportional to its wavelength.
Reason: Energy of the particle = Mass x (speed of light)2
- This reason is also true.
- According to Einstein's theory of relativity, the energy of a particle is given by the equation E = mc^2, where E is the energy, m is the mass, and c is the speed of light.
- This equation shows that mass and energy are interchangeable, and the energy of a particle is directly proportional to its mass.
- Therefore, the energy of a photon is directly proportional to its mass.
Explanation of the relationship between the assertion and reason:
- The assertion states that the mass of a moving photon varies inversely as the wavelength.
- The reason supports this assertion by explaining that the energy of a photon, which is directly proportional to its mass, can be calculated using the equation E = mc^2.
- As the wavelength of a photon decreases, its momentum and energy increase, resulting in an increase in mass according to the equation E = mc^2.
- Similarly, as the wavelength of a photon increases, its momentum and energy decrease, resulting in a decrease in mass.
- This inverse relationship between mass and wavelength is consistent with the assertion.
Conclusion:
- The assertion and reason are both true and the reason explains the assertion.
- Therefore, option 'A' is the correct answer.

The correct answer is option 'A', which states that both the assertion and reason are true and the reason explains the assertion.
