a) (vi) gamma ray, (i) x-ray, (vii) ultraviolet, (iv) visible, (ii) infrared, (iii) microwave, (v) radio wave
b) (v) radio wave, (iii) microwave, (ii) infrared, (iv) visible, (vii) ultraviolet, (i) x-ray, (vi) gamma ray
c) (v) radio wave, (iii) microwave, (iv) visible, (ii) infrared, (vii) ultraviolet, (i) x-ray, (vi) gamma ray
d) (vi) gamma ray, (i) x-ray, (iv) visible, (vii) ultraviolet, (ii) infrared, (iii) microwave, (v) radio wave

Answer 1

The correct order of the regions of the electromagnetic spectrum from shortest to longest wavelength is gamma rays, X-rays, ultraviolet, visible, infrared, microwaves, and radio waves, which corresponds to option (a).

Step-by-step explanation:

The electromagnetic spectrum consists of different types of radiation based on their frequency and wavelength. These types are gamma rays, X-rays, ultraviolet (UV), visible light, infrared (IR), microwaves, and radio waves. When arranging them in order of increasing wavelength, we start with gamma rays, which have the shortest wavelength, and end with radio waves, which have the longest.

The correct arrangement from shortest to longest wavelength is: (vi) gamma ray, (i) X-ray, (vii) ultraviolet, (iv) visible, (ii) infrared, (iii) microwave, (v) radio wave. Therefore, the correct answer from the options provided is option (a).
