C.1
What is "Amplitude" "Time Period" and "Frequency"
Maximum displacement
Time taken for 1 oscillation/cycle
Oscillations per second
State the Wave formula
(kinda easy) <- ture picked this one
V = wavelength*frequncy
T and 2T
What is the difference betwenn standing and travelling waves?
standing waves do not transfer energy and remains in a constant position whereas travelling waves move
If a wave has a wavelength of 0.03m and frequncy of 19Hz what is the velocity
0.57m/s
State the 2 conditions for SHM
The acceleration is directly proportional to the displacement from the equilibrium point
The acceleration is always acting towards the equilibrium point
What is a wavefront
Maximum POSITIVE displacement
Define constructive and decontructive interference
when the amplitude of the superposition is either larger or smaller than the amplitude of a single wave
What are anti nodes and nodes
Antinodes are maximum displacement and nodes are zero displacement.
How many times larger is the central maximum compared to the secondary maxima?
2 rimes
Why is there a negative symbol in the formula for SHM?
a = - ω^2x
Acceleration and displacement act in oppodite directions
What is the phase difference in degrees of 2/4landa
180 degrees
Why does white light seperate when passed through a prism?
Some colours get slowed down more than others bending the light and seperated.
Greater frequency = more bend = spread
(refraction)
How many nodes are there on the fundamental frequncy?
Define fundamental frequency
2
Lowest frequncy at which a standing wave is produced
How are standing waves porduced?
from the interference of 2 waves with constant frequencyt and amplitude
A spring with a spring constant of 125nm, is attached to a 5kg mass, stretched +5 meters and released
(horizontally on frictionless plane)
What is the angular frequency or frequency
5 rad-1 or 0.80Hz
FREEE FREEE FEEERRREEE DUDUDUDUDU FREEEE
GET SCREWED RURE TURNTALE CUZ U DIDNT GET IT
i hope ture didnt pick this
What is the refractive index of a vacuum or air?
1
Do waves in a open-open pipe exit at the anti-nodes or nodes?
anti-nodes
In what pipes are odd harmonics possible?
open-closed
A spring with a spring constant of 125nm, is attached to a 5kg mass, stretched +5 meters and released
(horizontally on frictionless plane)
What is themaximum velocity
v max = 5*5 =25
What is the difference between Transverse and Longitudinal waves?
Transverse travels perpendicular to the energy transfer
Longitudinal trabels parralel
FREEE FREEE FREEE GOOD JOB FOR TAKING RISKS FREEE DUDUDUDUD TUTUTU FREEEEEEEEE
lol ture didnt get it again
What is the difference between heavy and critical damping
critical damping reaches 0 at the fastest possible time
What are the 2 conditions for Total internal reflectiom?
Angle of incidence is larger than the critical angle
the refractive index of the incident material is greater than the refractive index of the refractive material
