I don't like any of the answers to #1 because long and high are relative terms. I know what a radio wave is but there are long radio waves and short radio waves. There are low frequencies and ultra high frequencies. Remember that c = 3E8 m/s (a constant) = wavelength x frequency. So when wavelength is a large number frequency must be a small number and when wavelength is a small number frequency is a large number. I think B fits but why not D also?
I think your answer to #2 is ok.
1. Which of the following correctly describes a radio wave?
A. long wavelength and high frequency
B. long wavelength and low frequency
C. short wavelengh and low frequency
D. short wavelengh and high frequency
Is the answer B?
2. When the energy of a light wave is transferred to a particle and causes it to vibrate and generate heat,the energy of light wave is
A. absorbed
B. reflected
C. refracted
D. transmitted
Is the answer A?
