- 1What is a Transverse wave ?The displacement is at a right angle to the wave direction. The wave moves up and down.
- 2What is a Longitudinal wave ?The dispacement is parallel to the wave direction . the waves move back and forth.
- 3What is displacement ?The distance wave moves a particle from its resting position.
- 4What is Amplitude ?The maximum displacement
- 5What is the wavelength?The distance between two similar points on the wave.
- 6What is periodic time ?The time between two similar events.
- 7What is Frequency ?The number of complete cycles per second.
- 8What equation links Time and frequency together? Extension :Can you rearrange it to ?Frequency = 1 divided by Time period.
Extension: Time period = 1 divided by Frequency - 9What do you do to get from 1000,000,000 (Giga) to 1000,000 (Mega)?x10 (9)
- 10What do you do to get from 0.000001 (micro) to 0.001 (milli) ?x10(-6)
- 11what are three ways the size of an out of phase wave can be expressed?Any of the below:
A distance
A time difference
A fraction of a cycle
An angle in degrees
An angle in radius - 12What is the equation that links velocity to distance ? Extension : Rearrange to find the DistanceVelocity = Distance decided by Time
Extension : Distance = Velocity x Time - 13What equation links velocity to wavelength? Extension : Rearrange to find the FrequencyVelocity = Frequency x Wavelength
Extension : Frequency = Velocity divided by Wavelength - 14What type of wave dose a tuning fork produce?A single reacting waveform
- 15What type of wave dose a musical estaminet produce ?A consistent note that is predominant to over tones.
- 16What type of wave dose a noise waveform produce? Extension : What causes the hissing noise waveform of a radio and TV?Non- repeated waveform
Extension: the tv or radio not being tuned. - 17what tree characteristics dose a musical note have ?1- Pitch
2- Loudness
3-Quality - 18what effects the three characterisations ?Pitch - is effected by Frequency
Loudness - is effected by amplitude
Quality - is effected by the waveform. - 19What is a Node ?A fixed point of a wave - due to the wave being exactly equal and opposite it is cancelled out.
- 20What is a anti-node?A point of a wave they add together to make double the wave size .
- 21How long is the distance between two Nodes or two Anti-nodes ?Half a wavelength.
- 22How long is the distance between a node and an anti-node ?One quarter of a wavelength.
- 23What is the lowest possible frequency on a standing wave called ?Fundamental Frequency ( 1st harmonic)
- 241: How many wavelengths dose the 1st fundamental frequency / 1st harmonic ? 2: How many wavelengths dose the 2nd fundamental frequency / 2nd harmonic/ 1st overtone have ? 3: How many wavelengths dose the 3rd fundamental frequency / 3rd harmonic/ 2nd overtone have ?1: Half a wave length
2: One wavelength
3: One and a half wavelength - 25What is the wavelength of the wave ?The length of the string divided by the number of complete cycles.
