The picture shows three light rays from the Sun

that are traveling toward Earth.
What happens to light ray X?
A. It is absorbed by space before it reaches Earth's
atmosphere.
B. It is reflected back into space by particles in
Earth's atmosphere.
C. It is slowed down into a sound wave when it hits
Earth's atmosphere.
D. It is transmitted around the planet by particles in
Earth's atmosphere.
6 The picture below shows how police can detect
speeding motorists using a radar gun to send
waves out and are bounced back. What
interaction of waves enables them to do this?
A. Waves reflect when they strike an object.
B. Waves diffract barriers.
C. Two waves combine, travel together, and form a
new wave.

1 answer

Let's analyze the questions individually.

  1. What happens to light ray X?

    • A. It is absorbed by space before it reaches Earth's atmosphere. - This is unlikely, as light from the Sun travels through space and reaches Earth.
    • B. It is reflected back into space by particles in Earth's atmosphere. - Some light is reflected, but not all; some will enter the atmosphere.
    • C. It is slowed down into a sound wave when it hits Earth's atmosphere. - This is incorrect. Light does not become sound when it enters the atmosphere.
    • D. It is transmitted around the planet by particles in Earth's atmosphere. - While some light can scatter, this option is somewhat misleading; "transmitted" implies more continuation without interaction.

    The most appropriate answer, depending on the context given in the picture, could be B, or possibly D, but B seems to capture the idea of reflected light.

  2. What interaction of waves enables police to detect speeding motorists using a radar gun?

    • A. Waves reflect when they strike an object. - This is the correct answer. Radar guns work based on the reflection of waves when they hit an object (in this case, a vehicle).
    • B. Waves diffract barriers. - This refers to the bending of waves around obstacles, which is not how radar guns function.
    • C. Two waves combine, travel together, and form a new wave. - This refers to wave interference, which is not the primary principle for how radar guns work.

In conclusion:

  1. The best answer for what happens to light ray X is B.
  2. The correct answer for the radar gun interaction is A.
