Even the music we listen to deals with how energy travels to get to our car radio. If an FM Radio station broadcasts its music at 97.7 MHz find the wavelength in angstroms of the radio waves. One angstrom is equal to 10^-10 m.

The distance between the earth and the sun is 1.496 x 10¹⁷ μm. How long (in mins) will it take for light to go from the sun to earth?

The speed of sound in dry air at 20 °C is 343 m/s and the lowest frequency sound wave that the human ear can detect is approximately 20 Hz. (a) What is the wavelength of such a sound wave?

A popular kitchen appliance produces electromagnetic radiation with a frequency of 2450 MHz. With reference to Figure 6.4, answer the following: (a) Estimate the wavelength of this radiation.

(a) What is the frequency of radiation that has a wavelength of 10 µm, about the size of a bacterium?

(d) What distance does electromagnetic radiation travel in 0.38 ps?
