Vedclass · Answer

(B) $1$. Frequency $(
u)$ is the number of waves passing a point per second. Given: $750$ waves in $1$ minute ($60$ seconds). $
u = \frac{750}{60} = 12.5 \ Hz$. $2$. The relationship between speed of light $(c)$,frequency $(
u)$,and wavelength $(\lambda)$ is $c = 
u 	imes \lambda$. $3$. Using $c = 3 	imes 10^8 \ m/s$: $\lambda = \frac{c}{
u} = \frac{3 	imes 10^8}{12.5} = 0.24 	imes 10^8 \ m = 2.4 	imes 10^7 \ m$. Therefore,the correct option is $B$.

List-$I$	List-$II$
$(1)$ $X$-rays	$(A)$ $\nu = 10^0 - 10^4 \ Hz$
$(2)$ Ultraviolet $(UV)$ rays	$(B)$ $\nu = 10^{10} \ Hz$
$(3)$ Long radio waves	$(C)$ $\nu = 10^{16} \ Hz$
$(4)$ Microwave	$(D)$ $\nu = 10^{18} \ Hz$

$750$ waves of an energy radiation pass in one minute from a point. What will be the wavelength of the radiation? (Assume the speed of radiation is $3 \times 10^8 \ m/s$)
