The ozone layer absorbs

The frequency range from $3 \times 10^9 \, Hz$ to $3 \times 10^{10} \, Hz$ is known as:

If $\lambda_v$,$\lambda_x$,and $\lambda_m$ are the wavelengths of visible light,$X$-rays,and microwaves respectively,then which of the following is correct?

Which rays are not a portion of the electromagnetic spectrum?

Arrange the following in the ascending order of wavelength :
$(A)$ Gamma rays $(\lambda_1)$
$(B)$ $X$-rays $(\lambda_2)$
$(C)$ Infrared waves $(\lambda_3)$
$(D)$ Microwaves $(\lambda_4)$
Choose the most appropriate answer from the options given below :

The correct match between the entries in column $I$ and column $II$ is:
$I$ (Radiation) | $II$ (Wavelength)
$(a)$ Microwave | $(i)$ $100 \, m$
$(b)$ Gamma rays | $(ii)$ $10^{-15} \, m$
$(c)$ $A.M.$ radio waves | $(iii)$ $10^{-10} \, m$
$(d)$ $X$-rays | $(iv)$ $10^{-3} \, m$
