# Not as "light" as it looks

Level pending

In photoelectric effect, we have the equations for particle nature of light i.e., for photons,

$p = \frac{h}{\lambda}$ $E = pc$

where,
$$p$$ is the momentum of a photon
$$E$$ is the energy of a photon
$$c$$ is the speed of light in air
$$h$$ is the Planck's constant
$$\lambda$$ is the wavelength of the light

Hence we can conclude that ,
