What is the definition of Period (T)?
The time it takes for one complete wave cycle, measured in seconds (s).
What is the definition of Frequency (f)?
The number of wave cycles that happen in one second, measured in hertz (Hz).
What is the definition of Amplitude (A)?
The maximum displacement of the wave from its equilibrium position.
What is the definition of Wavelength (ฮป)?
The distance between two corresponding points on consecutive waves.
Define angular frequency (ฯ).
Angular frequency is defined as $\omega = 2\pi f$, where f is the frequency.
What are the differences between Period and Frequency?
Period: Time for one cycle, measured in seconds. | Frequency: Cycles per second, measured in Hertz; they are inversely proportional.
Compare the effects of high vs. low frequency sound waves.
High frequency: High pitch sound, like a dog whistle. | Low frequency: Low pitch sound, like a bass guitar.
Compare the effects of high vs. low frequency light waves.
High frequency: Higher energy waves, like UV light. | Low frequency: Lower energy waves, like infrared light.
What happens when the frequency of a wave increases, while the speed remains constant?
The wavelength decreases.
What happens when the speed of a wave doubles, while the frequency remains constant?
The wavelength doubles.
What happens when the amplitude of a wave is doubled?
The energy of the wave quadruples.
What is the effect of increasing the frequency of a sound wave?
The pitch of the sound increases.
