No Multiple Choise Or True Or False. Questions on Waves And Transverse And Longitudinal And Formulas Gcse Level Flashcards
What is a wave?
A wave is a disturbance that transfers energy through matter or space.
What are the two main types of waves?
Transverse waves and longitudinal waves.
In a transverse wave, how do the particles of the medium move?
The particles move perpendicular to the direction of wave propagation.
In a longitudinal wave, how do the particles of the medium move?
The particles move parallel to the direction of wave propagation.
What is the wavelength of a wave?
The wavelength is the distance between consecutive crests or troughs in a transverse wave or between compressions in a longitudinal wave.
What is frequency in the context of waves?
Frequency is the number of waves that pass a given point in one second.
What is the formula for wave speed?
Wave speed (v) is calculated as v = frequency (f) × wavelength (λ).
What unit is used to measure frequency?
Hertz (Hz).
What is amplitude in a wave?
Amplitude is the maximum displacement of points on a wave from the rest position.
What is the relationship between wavelength and frequency?
Wavelength is inversely proportional to frequency; as frequency increases, wavelength decreases.
What is a compression in a longitudinal wave?
A compression is a region where particles are closest together.
What is a rarefaction in a longitudinal wave?
A rarefaction is a region where particles are spread apart.
What is the principle of superposition?
The principle of superposition states that when two or more waves overlap, the resultant displacement is the sum of the individual displacements.
What is constructive interference?
Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.
What is destructive interference?
Destructive interference occurs when two waves meet out of phase, resulting in a wave of lesser amplitude.
What is the relationship between period (T) and frequency (f)?
The period is the reciprocal of frequency; T = 1/f.
What is the SI unit of wavelength?
Meters (m).
What type of wave is light?
Light is an electromagnetic wave.
What is a standing wave?
A standing wave is a wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.
What is resonance in the context of waves?
Resonance is the phenomenon that occurs when a system is driven at its natural frequency, resulting in large amplitude oscillations.
What is the Doppler effect?
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.
What is the formula to calculate the speed of sound in air?
The speed of sound in air can be approximated using the formula v = 331 + (0.6 × T) where T is the temperature in degrees Celsius.
What is a wavefront?
A wavefront is an imaginary surface representing points of a wave that oscillate in phase.
What is diffraction?
Diffraction is the bending of waves around obstacles or through openings.
