Question 366: Dual Nature of Matter and Radiation

Question

When light of wavelength '$$\lambda$$' is incident on a photosensitive surface, photons of power 'P' are emitted. The number of photon 'n' emitted in time 't' is [h = Planck's constant, c = velocity of light in vacuum]

Accepted Answer

Power $$\mathrm{P=\frac{Energy}{t}=\frac{nhc}{\lambda t}}$$
$$	herefore \mathrm{n=\frac{P\lambda t}{hC}}$$

Answer

$$\mathrm{\frac{hc}{p\lambda t}}$$

Answer

$$\mathrm{\frac{P\lambda}{htc}}$$

Answer

$$\mathrm{\frac{P\lambda t}{hc}}$$

Answer

$$\mathrm{\frac{hP}{\lambda tc}}$$
