Question

What is the doppler effect used to measure at baseball games?

O temperature
O moving clouds
O weather
O speed

Answer 1

The Doppler effect is used to measure the speed of a baseball at baseball games by analyzing the change in frequency of the sound waves produced by the baseball. Hence, the last option is correct.

Step-by-step explanation:

The Doppler effect is commonly used to measure the speed of objects, including at baseball games. In the context of baseball games, the Doppler effect is used to measure the speed of a baseball. When a baseball is thrown toward the batter, the sound waves it produces are compressed, resulting in a higher frequency.

Conversely, when a baseball is moving away from the batter, the sound waves are stretched, resulting in a lower frequency. By measuring the change in frequency of the sound waves, the Doppler effect can be used to determine the speed of the baseball.
