🌊 Wave Concepts: Frequency, Longitudinal, and Transverse Waves
Question 1
How often a wave cycle is completed is referred to as:
- (a) Amplitude
- (b) Wavelength
- (d) Period
- (e) Frequency
✅ The phrase “how often a wave cycle is completed” describes the wave’s frequency, which measures the number of cycles per unit time.
Answer: (e) Frequency
Answer: (e) Frequency
Question 2
If energy is transferred parallel to the direction of motion of the wave, then it must be a:
- (a) Transverse wave
- (b) Longitudinal wave
✅ When the energy is transferred parallel to the direction of motion of the wave, the wave is a longitudinal wave.
In a longitudinal wave, the oscillations occur in the same direction as the propagation of the wave (e.g., sound waves in air).
Answer: (b) Longitudinal wave
In a longitudinal wave, the oscillations occur in the same direction as the propagation of the wave (e.g., sound waves in air).
Answer: (b) Longitudinal wave
Question 3
If energy is transferred perpendicular to the direction of motion of the wave, then it must be a:
- (a) Transverse wave
- (b) Longitudinal wave
✅ When the energy is transferred perpendicular to the direction of motion of the wave, the wave is a transverse wave.
In transverse waves, the oscillations are at right angles to the direction of travel (e.g., electromagnetic waves and waves on a string).
Answer: (a) Transverse wave
In transverse waves, the oscillations are at right angles to the direction of travel (e.g., electromagnetic waves and waves on a string).
Answer: (a) Transverse wave
