The frequency of electromagnetic wave A is twice that of electromagnetic wave B. For these two waves, what is the ratio of the wavelengths λA / λB  in a vacuum?Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer.aλA / λB = 2, because wave A has twice the speed that wave B has.bλA / λB = 2, because wave A has one-half the speed that wave B has.cλA / λB = ½ , because wave A has one-half the speed that wave B has.dλA / λB = ½ , because wave A has twice the speed that wave B has.eλA / λB = ½ , because both waves have the same speed.

Wave X has the same frequency as wave Y. If wave X has twice the wavelength of Y, how does the speed of X compare to Y?A X has 1414 the speed of Y.B X has 1212 the speed of Y.C X has the same speed as Y.D X has twice the speed of Y.
