QuestionQuestion 5 ( 0.25 points) Sound intensity decreases with distance from the source. True False
Studdy Solution
STEP 1
1. Sound intensity refers to the power per unit area carried by a sound wave.
2. The sound source emits sound waves uniformly in all directions.
STEP 2
1. Understand the concept of sound intensity.
2. Analyze how distance affects sound intensity.
3. Determine the truth value of the statement.
STEP 3
Understand the concept of sound intensity:
Sound intensity is defined as the power per unit area carried by a sound wave. It is often measured in watts per square meter ().
STEP 4
Analyze how distance affects sound intensity:
Sound intensity decreases with distance from the source because the energy of the sound wave spreads out over a larger area. This is described by the inverse square law, which states that intensity is inversely proportional to the square of the distance from the source.
STEP 5
Determine the truth value of the statement:
Given the inverse square law, the statement "Sound intensity decreases with distance from the source" is true.
The statement is:
