  • Q2

    A student wants to develop a model that demonstrates the transmission of waves. Which concept should the student include in the model to show how the transmission of visible light is different from the transmission of sound waves?

    Question Image

    Light and sound waves can be transmitted through space.

    Light can be transmitted through different forms of matter, but sound waves can only be transmitted through space.

    Light can be transmitted through space and matter, but sound waves can only be transmitted through matter.

    Light can be transmitted only through space, and sound waves can be transmitted through space and matter.

  • Q3

    Based on the behavior of these visible light rays, which claim can be made about materials A or B?

    Question Image

    Material A is transparent because the light ray is transmitted.

    Material A is transparent because the light ray is absorbed.

    Material B is transparent because the light ray is transmitted.

    Material B is transparent because the light ray is absorbed.

  • Q5
    What happens after sensory receptors detect a bright light?
    They transmit sound waves to alert the brain.
    They send signals to the brain, which processes the information and may adjust pupil size.
    They immediately cause the eyes to close without brain involvement.
    They convert the light into vitamins stored in the eye.

  • Q6
    Which of the following best describes the process that occurs when you touch a hot surface?
    Your muscles automatically react without involving the brain.
    The skin begins to sweat to cool down the surface.
    The hot surface transfers energy directly to the nerves, bypassing the brain.
    Sensory receptors in the skin detect the heat and send signals to the brain, resulting in a quick reaction.
