Simple Harmonic Motion
This type of motion is characterized by acceleration directed towards a fixed point and proportional to displacement.
What is simple harmonic motion
This quantity is defined as the number of complete oscillations passing a point per second.
What is frequency?
This law states that for a given pair of media, the ratio sini/sinr is constant.
What is Snell's Law?
The type of wave that is responsible for hearing in humans.
What is a longitudinal wave?
Vision occurs because light from objects enters the eye and is focused on this structure.
What is the retina?
In SHM, displacement x can be described by this function involving amplitude A, angular frequency ω, and time t.
What is x=Asin(ωt) or x=Acos(ωt)?
In the wave equation y=Asin(ωt−kx), this quantity determines how rapidly the wave oscillates in time and is equal to 2πf.
What is angular frequency?
This optical phenomenon occurs when the angle of incidence exceeds the critical angle at a boundary from denser to rarer medium.
What is total internal reflection?
This is the approximate frequency range of sound audible to a healthy human ear.
What is 20 Hz to 20 kHz?
The eye behaves optically like this type of lens system.
What is a converging (convex) lens system?
Velocity in SHM is zero at this point of the motion.
What is the maximum displacement?
For a sinusoidal wave on a stretched string, this physical quantity is directly proportional to the square of the amplitude and the square of the frequency.
What is the intensity of a wave?
This expression gives the critical angle C for light travelling from a medium of refractive index n into air.
What is sinC=1/n?
This perceptual property of sound is primarily determined by frequency.
What is pitch?
This process allows the eye to focus on objects at different distances.
What is accommodation?
SHM can be represented as the projection of this type of uniform motion onto one axis.
What is uniform circular motion?
A string fixed at both ends vibrates at its third harmonic. This is the relationship between the string length L and the wavelength.
What is L=3lambda/2
This physical quantity remains constant when light passes from one medium to another, even though its speed and wavelength change.
What is frequency?
The ear’s ability to detect a wide range of sound intensities is due to this logarithmic response.
What is the decibel scale?
This defect of vision occurs when distant objects are focused in front of the retina.
What is myopia?
For a mass m on a spring with spring constant k, the period is given by this formula.
What is T=2πmk
This CAPE-level expression gives the intensity of a transverse wave on a stretched string in terms of density, frequency, velocity, and amplitude.
I=2π2f2μvA2
Regardless of object position, a diverging lens always forms an image with this set of properties.
What is virtual, upright, and diminished?
This part of the ear helps to collect and funnel sound waves into the ear canal.
What is the pinna?
Hypermetropia is corrected using this type of lens
What is a converging (convex) lens?
