Question

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 remains the same. d randomly changes.

Explanation:

Radio waves are electromagnetic waves, so their speed \( c \) (speed of light) is constant. The relationship between speed, frequency (\( f \)), and wavelength (\( \lambda \)) is \( c = \lambda f \). When frequency \( f \) increases (tuning to higher FM), since \( c \) is constant, wavelength \( \lambda=\frac{c}{f} \) must decrease.

Answer:

B. decreases.
