Infrared photon has more energy than the photon of visible light

Vedclass · Answer

(A) The energy of a photon is given by the formula $E = \frac{hc}{\lambda}$,where $h$ is Planck's constant,$c$ is the speed of light,and $\lambda$ is the wavelength.From this relation,we see that $E \propto \frac{1}{\lambda}$,meaning energy is inversely proportional to wavelength.Infrared radiation has a longer wavelength than visible light. Therefore,infrared photons have less energy than visible light photons.Statement $A$ claims that infrared photons have more energy than visible light,which is incorrect.Photographic plates can be made sensitive to both ultraviolet and infrared rays,making statements $B$ and $C$ correct.Infrared rays,like visible light,travel in straight lines and are blocked by opaque objects,thus they can cast shadows,making statement $D$ correct.

List-$I$	List-$II$
$(a)$ Ultraviolet rays	$(i)$ Study crystal structure
$(b)$ Microwaves	$(ii)$ Greenhouse effect
$(c)$ Infrared waves	$(iii)$ Sterilizing surgical instruments
$(d)$ $X$-rays	$(iv)$ Radar system
