Consider your favorite radio station. am radio has a frequency between 535 kilohertz and 1605 kilohertz, and fm radio has a frequency between 88 megahertz and 108 megahertz. calculate the wavelength and the energy of the electromagnetic waves from your favorite radio station.

What would the difference of spectral lines emitted by hydrogen gas in distant galaxies which is normally found at a wavelength of 21 cm on earth, be observed at 21.1 centimeters?

Which statement correctly describes the relationship between frequency and wavelength?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
