Question

calculate the mass of a photon with wavelength 3.6Å ?​

Answer 1

Answer:

Desy Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely "no": the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.

★wavelength = 3.6Å

$3.6 \times {10}^{ - 10} m$

$v = 3.0 \times {10}^{8} m \: \: s$

$= > wavelength = \frac{h}{mv}$

$= > \frac{6.626 \times {10}^{ - 34} }{3.6 \times {10}^{ - 10} \times 3.0 \times {10}^{8} }$

$= > 8967 \times {10}^{ - 10}$
