  1. 1. The images above show particles in a medium. Which of the following shows the worst conditions for a sound wave travel?
    A
    B
    C
    D
    is the answer A?
    I don't see any images. I recopied all of this since you didn't number them.

    2. Which of the following correctly describes a radio wave?
    A long wavelength and high frequency
    B long wavelength and low frequency
    C short wavelength and low frequency
    D short wavelength and high frequency
    is the answer B?
    B is correct but so is D. I have operated radios on 180 m(long wavelength) and about 1700 kHz AS WELL AS 2 m (short wavelength) and 144 mHz (high frequency).

    3. When the energy of a light wave is transferred to a particle and causes it to vibrate and generate heat, the energy of the light wave is
    A absorbed
    B reflected
    C refracted
    D transmitted
    is the answer A?
    yes

    4. On the light wave above, the property indicated by the arrow determines which characteristic of light?
    A brightness
