Mechanical Waves and Sound
How many waves pass an observer in one second if they have a frequency of 5 Hz?
20 waves
5 waves
10 waves
50 waves
A string fixed at both ends has its tension increased during resonance until a particular harmonic shape is achieved; if all other variables remain constant except length halved, how does this affect its resonant frequency?
The innovative design relies on reusable materials for construction which can be returned back into supply chains after use dramatically cutting waste management costs.
The resonant frequency quadruples since it is inversely proportional to square of length according .
The resonant frequency doubles because fundamental frequency is inversely proportional directly proportional only once not squared with length.
The resonant frequency remains unchanged because altering length does not affect velocity or standing wave patterns established on string.
Which scenario would result in a standing wave pattern on a string fixed at both ends?
The string vibrates at a frequency between its natural frequencies.
The string vibrates at one of its natural frequencies.
The string vibrates with an amplitude larger than its maximum stable amplitude.
The tension in the string is continuously changed while vibrating.
In a standing wave pattern formed by two identical traveling opposite directions, what term is used to describe the areas of minimal movement?
Beat frequencies
Antinodes
Nodes
Resonance cavities
In the context of periodic waves, what does the wavelength represent?
The time it takes for one full vibration of a particle in medium
The rate at which energy is transferred by the wave
The height from the center line to the peak of the wave
The distance between two consecutive similar points on the wave
What is the unit of frequency for periodic waves in physics?
Joules (J)
Meters per second (m/s)
Hertz (Hz)
Newtons (N)
In a transverse wave, what is the direction of particle displacement relative to wave motion?
At a 45-degree angle to the wave motion
Randomly with respect to wave motion
Perpendicular to the wave motion
Parallel to the wave motion

What property of a wave represents the maximum displacement from its rest position?
Speed
Amplitude
Wavelength
Frequency
A circular ripple tank experiment shows two points equidistant from source vibrating synchronously but differ how?
Crest appears higher at one than at the other.
Crest meets trough exactly halfway between them, making flat surface.
No visible difference since symmetry means vibrations would be indistinguishable.
Ripples form concentric circles around one and spiral patterns around second.
What measurement describes the height from the rest position to the crest or trough of a wave?
Period
Velocity
Intensity
Amplitude
