Question

In a laser action the energy of stimulated photon is
39.6 x 10^-20. What
is the wavelength of stimulated
Photon ??​

Answer 1

Answer:

5*10^3(approx)

Explanation:

so as we know the formula for energy of photon is E=HV

and we got energy E = 39.6 * 10^-20

h = plancks constant = 6.626*10^-34

v = frequency

as we know v = c/lambda

=>  E = HC/LAMBDA---(1)

and c is the speed of light C = 3*10^8 m/s

substitute given values in 1

then we get LAMBDA(WAVELENGTH) = 5*10^3(approximately)
