Study Notes
Physics Test - Vibration and Waves
-
Question 1: Correct statements about vibration are: Movement with uniform period, and one-direction motion is incorrect. Back and forth motion is correct.
-
Question 2: The number of full vibrations per second is frequency.
-
Question 3: To make a pendulum swing faster, reduce the length of the rope.
-
Question 4: Examples of electromagnetic waves are light waves and radio waves.
-
Question 5: Statements about sound waves are mechanical waves and their propagation direction is perpendicular to vibration.
-
Question 6: Analyzing waves X,Y, and Z:
- Wave X has the greatest amplitude.
- Waves X and Y have the same period.
- Wave Z has a higher frequency than wave Y.
- Wave Z has a longer period than wave X .
- Wave X has the highest frequency.
