The frequency of a wave is $6 \times 10^{15} \text{ Hz}$. This wave is:

The wavelengths of short radio waves,$X$-rays,and ultraviolet waves are $\lambda_{1}$,$\lambda_{2}$,and $\lambda_{3}$ respectively. Arrange them in decreasing order.

If microwaves,$X$ rays,infrared,gamma rays,ultraviolet,radio waves and visible parts of the electromagnetic spectrum are denoted by $M, X, I, G, U, R$ and $V$ respectively,then which of the following is the arrangement in ascending order of wavelength?
