Question

calculate the number of photons in calculate the number of photons of light of wavelength 3960 necessary to provide 1 joule of energy ​

Answer 1

Answer:

(1) Given: The wavelength is 3960 A. The energy is 1 J.

(2) To find; The number of photons of light in the wavelength.

(3) Solution: The formula for the number of photons be. N= E×λ/h×c. Putting the above values. N=1J×3960×10⁻¹⁰/(6.26×10⁻³⁴)×3×10⁸ N=210.86×10¹⁶ Therefore the number of photons be 210 ×10¹
