Which sequence shows the different types of electromagnetic waves arranged in an increasing order of their frequency?

a.)radio waves, microwaves, visible light, x-rays
b.)x-rays, visible light, microwaves, radio waves
c.)visible light, radio waves, x-rays, microwaves
d.)microwaves, x-rays, radio waves, visible light
e.)visible light, x-rays, radio waves, microwaves

The correct answer is the option A which is radio waves, microwaves, visible light, x-rays.

Explanation:

Electromagnetic spectrum is the graph describing the ranges of frequencies of different electromagnetic waves.As frequency and wavelength are inversely proportional.The waves with long wavelength have low frequency and waves with short wavelength have high frequency.Rdiowaves have long wave length and low frequency and microwaves have frequency more than radio waves and visible waves have high but x rays have of frequency of all given in list.Hence on the bases of frequency:Radio waves ≤ Micro waves ≤ Visible waves ≤ x-raysIt can be seen in given electromagnetic spectrum.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
