Question

If we denote microwaves, X rays, infrared, gamma rays, ultra-violet, radio waves and visible parts of the electromagnetic spectrum by M, X, I, G, U, R and V, the following is the arrangement in ascending order of wavelength :

• A. R, M, I, V, U, X and G
• B. M, R, V, X, U, G and I
• C. G, X, U, V, I, M and R
• D. I, M, R, U, V, X and G

Answer 1

The correct option is C G, X, U, V, I, M and R

Answer is C.
From the electromagnetic spectrum, we know the ascending order of wavelength is
$G<X<U<V<I<M<R$
