As you tune your radio to a higher frequency, from 88.5 fm to 103.3 fm, the wavelength of the wave that you are tuning in a increases b decreases c stays the same d randomly changes

the relation that relates the speed of wave, frequency of wave and wavelength is given as

wavelength =

the speed of wave in a medium remains constant. hence the wavelength is inversely related to the frequency of wave.

that means, as the frequency is increased, the wavelength decreases and vice versa.

hence the correct choice is

B decreases

v 154.9= 0.9 length length s little over 154.9cm

d) physical means can be used to separate the components of air.
