3.1 Progressive waves

Cards (67)

Stationary waves oscillate at fixed locations without transferring energy
The phase difference in a stationary wave remains constant. 
True
In a progressive wave, there is a varying phase difference between different points
In transverse waves, the oscillation is perpendicular to the wave direction. 
True
What is a progressive wave?
Energy transfer without medium
Match the wave property with its description:
Energy Transfer ↔️ Transfers energy for progressive waves
Wavefront ↔️ Travels in a direction for progressive waves
Phase Difference ↔️ Varies for progressive waves
A progressive wave transfers energy without transferring the medium
Match the wave property with its behavior in progressive or stationary waves:
Energy Transfer ↔️ Transfers energy in progressive waves
Wavefront ↔️ Travels in progressive waves
Phase Difference ↔️ Varies in progressive waves
In longitudinal waves, the oscillation is parallel to the direction of wave travel
The relationship between wave speed, frequency, and wavelength is given by the equation $v =$ $f \lambda$  
True
A progressive wave transfers energy from one point to another without transferring the medium
In longitudinal waves, the particle motion is parallel to the wave direction. 
True
Wave speed is measured in meters per second
The number of wave cycles that pass a given point per unit of time is called frequency
What is the wave speed if a wave has a frequency of 2 Hz and a wavelength of 3 meters?
6 m/s
Progressive waves transfer energy, while stationary waves do not transfer energy
What is an example of a longitudinal wave?
Sound wave
The period of a wave is the time for one complete wave cycle. 
True
In one period, a wave travels one wavelength. 
True
The period and frequency of a wave are inversely related.
True
What is the definition of wave speed?
Distance traveled by the wave per unit time
What is the relationship between period and frequency?
$T =$ $\frac{1}{f}$
If a wave has a frequency of 2 Hz and a wavelength of 3 meters, what is the wave speed?
6 m/s
The principle of superposition leads to constructive or destructive interference
If two waves with amplitudes 3 and 4 meters meet in phase, the resultant amplitude is 7 meters 
True
Interference patterns can be observed in sound and light waves 
True
Diffraction is caused by Huygens' principle, where each point acts as a source of new spherical waves
True
In a progressive wave, energy is conveyed while matter remains stationary. 
True
What happens to energy transfer in a stationary wave?
It does not transfer energy
What is conveyed through the medium in a progressive wave?
Energy
What distinguishes transverse waves from longitudinal waves?
Oscillation direction
Match the wave parameter with its definition:
Amplitude ↔️ Maximum displacement of wave
Wavelength ↔️ Distance between wave crests
Period ↔️ Time for one wave cycle
Frequency ↔️ Cycles per unit time
Wave speed ↔️ Speed of wave propagation
Match the wave parameter with its definition:
Amplitude ↔️ The maximum displacement of the wave from its resting position
Wavelength ↔️ The distance between two consecutive wave crests or troughs
Period ↔️ The time taken for one complete wave cycle
Frequency ↔️ The number of wave cycles that pass a given point per unit of time
Wave speed ↔️ The speed at which the wave propagates through the medium
A stationary wave oscillates at fixed locations without transferring energy
The wave equation $v =$ $f\lambda$ can be derived using the relationships between period, frequency, and speed. 
True

The wave equation is $v =$ $f \lambda$ . 
True
Match the wave type with its energy transfer property:
Progressive wave ↔️ Transfers energy
Stationary wave ↔️ Does not transfer energy
Longitudinal waves create compressions and rarefactions
The wave equation relates wave speed, frequency, and wavelength
