- 1In an oscillation, when at equilibrium what is the acceleration?Acceleration is 0 when at equilibrium, this is due to no net force.
- 2What are the two things that effect the oscillation of a spring? Of a pendulum?For a spring it is the spring constant (k) and the mass.
For the pendulum it is the gravity (g) and the length of the string. - 3The speed of a wave on a string depends on what? (2 things)The tension in the string and the mass per unit length of the string.
- 4What is the difference between transverse waves and longitudinal waves?Longitudinal waves have a disturbance parallel to the wave while transverse is perpendicular to the wave.
- 5Which wave type is all sound? (2 things)Its a longitudinal, mechanical wave.
- 6The longest wave that can fit the space allowed for is called __________.A fundamental.
- 7What is the Doppler effectMotion effects perceived frequency, as the sound producer gets closer to you there is a higher frequency perceived, and if moving away it has a lower perceived frequency.
- 8When a wave hits a boundary it ____. (3 things can happen)1) Reflection-Energy bounces off barrier
2)Transmission- Energy passes through the medium.
3) Absorption-Enters material, but dissipated rather than transmitted. - 9What happens when waves pass through each other?They become superimposed--meaning that their effects are combined.
- 10What is the wavelength and frequency expressions for Strings, Open tubes, and Closed Tubes.Strings and Open tubes: λ=2L/n and f=nv/2L
Closed Tubes: λ=4L/n and f=nv/4L
(Note that in closed tubes there is no resonance at the even harmonics)
