Question

3) Please circle the correct answers, if there is no correct answer, then leave it blank(do not circle.)

1.

a) the velocity of electromagnetic waves increases with the frequency of the wave.

b) the velocity of visible light waves is the same, however other types of electromagnetic waves has different velocities depending on the frequency.

2.

a) as the wavelength of the wave increases, the frequency increases, and the velocity decreases.

b) as the wavelength of the wave increases, the frequency stays constant.

3.

a) the product of wavelength and frequency of a wave is the velocity of the wave.

b) the quotient of wavelength and frequency of a wave is the velocity of the wave.

4.

a) red light has a smaller wavelength and lower frequency than blue light.

b) red light has a longer wavelength and higher frequency than blue light.

5. Since sound travels at about 340 m/s in air, we can see that

a) electromagnetic waves travel slower than sound if air is present.

b) electromagnetic waves cannot travel in air.
