- Which statement below is false? O The wavelength of light is the distance between two corresponding points in the wave pattern O The frequency of the light is the number of waves that pass a given point in a second The higher the frequency of light, the longer the wavelength The frequency of light increases as wavelength decreases The higher the frequency of light, the greater its energyA rocket ship floating in empty space suddenly turns on its engines and begins to rapidly accelerate toward the earth. In the first second of the acceleration, what effect would you see in the wavelength of radio signals beamed from the spacecraft back toward the earth? a) The wavelength would suddenly become shorter because the ship is now moving toward us. b) The wavelength would be unaffected because the acceleration in the first second would not yet produce a significant velocity. c) The wavelength would be longer because the transmitter is in an accelerated frame and the equivalence principle states it would slow down like a clock in a gravitational field. d) The wavelength would be shorter because the transmitter is in an accelerated frame and the equivalence principle states that it would speed up like a clock coming toward us.1:24 G O O * N 5GUC I 67%, Show What You Know: Learning... KO> O 5 de 8 A new band sensation is playing a concert and recording it for a live album to be released this summer. Select all the statements that are true for when the recorded sound moves through the speaker. The frequency or amplitude of the waves will not change. The speaker changes the wave from O mechanical wave to an electromagnetic wave. The speaker changes the wave from an O electromagnetic wave to a mechanical wave. The waves from the speaker are electromagnetic waves. The frequency or amplitude of the waves could change. The waves from the speaker are mechanical waves. The speaker does not change the wave type.

(a) What is the wavelength of the radio waves produced by this station? (b) Estimate the average intensity of the wave at a distance of 36.1 km from the radio transmitting antenna. Assume for the purpose of this estimate that the antenna radiates equally in all directions, so that the intensity is constant over a hemisphere centered on the antenna. (c) Estimate the amplitude of the electric field at this distance.S15
