1/15뒤로Skip to main content뒤로What is the definition of a wave?
A wave is a disturbance in space that requires a medium to travel through. What is a medium in the context of waves?
A medium is the material or substance that a wave travels through, such as air, water, or a string. What are the two main types of waves discussed in this lesson?
The two main types are transverse waves and longitudinal waves. How do particles move in a transverse wave?
In a transverse wave, particle displacement is perpendicular to the direction of wave motion. How do particles move in a longitudinal wave?
In a longitudinal wave, particle displacement is parallel to the direction of wave motion. What is the wavelength in a transverse wave?
Wavelength is the horizontal distance between successive crests or troughs in a transverse wave. What is the wavelength in a longitudinal wave?
Wavelength is the distance between successive regions of maximum compression in a longitudinal wave. What is amplitude in a transverse wave?
Amplitude is the height from the equilibrium position (x-axis) to the crest or trough of the wave. Does amplitude matter in longitudinal waves?
Amplitude does not really matter in longitudinal waves. What is the formula for wave speed?
Wave speed (V) is given by V = λ × f, where λ is wavelength and f is frequency. How are period and frequency related?
Period (T) and frequency (f) are inverses of each other: f = 1/T. How do you calculate wavelength if you know wave speed and frequency?
Wavelength (λ) is calculated by dividing wave speed (V) by frequency (f): λ = V/f. What is the wavelength of a sound wave with speed 343 m/s and frequency 260 Hz?
The wavelength is 1.32 meters, calculated by λ = 343/260. What is the horizontal distance from crest to crest called?
It is called the wavelength. What is the time it takes for a wave to complete one cycle called?
It is called the period (T).
