  1. Which type of wave needs a medium to travel?
    sound waves, because they travel by oscillating electromagnetic fields
    light waves, because they travel by oscillating molecules
    light waves, because they travel by oscillating electromagnetic fields
    ***sound waves, because they travel by oscillating molecules***

    What do both sound and light waves transfer?
    ***energy***
    electricity
    air
    matter

    How does an increase in amplitude affect sound and light waves?
    ***louder sound and brighter light***
    higher-pitched sound and longer wavelengths for light
    higher-pitched sound and brighter light
    louder sound and longer wavelengths for light

    What happens to the wavelength when the frequency increases?
    The wavelength increases
    ***The wavelength decreases***
    The wavelength increases if the speed increases
    The wavelength stays the same

    Which of the following is true about sound waves?
    Sound would move faster in a pool of water than in a pool of Jello
    Sound would move faster in a pool of rubber than in a pool of diamonds
    ***Sound moves faster in the ocean than in the air***
    Sound moves faster in a lake than in the ocean

    5/5, I promise! If not, then I am extremely sorry!
