Physics- Waves

1

What do waves carry from one place to another?

1

What is the wavelength of a wave?

1

What is the frequency of a wave?

1

What is the amplitude of a wave?

1

The formula for frequency is 1/time period

1

What is the wave equation?

1

The direction of vibration for transverse waves is ( perpendicular, parallel ) to the direction of travel where as for longitudinal waves it is ( parallel, perpendicular ) to the direction travel

1

The phase is

1

The phase angle can also be written as fractions of wavelengths, degrees or radians;
360 degrees = ( 1, 1/2, 1/4, 3/4 ) wavelength = ( 2n, 1/2n, 3/2n, 1n ) radians
180 degrees = ( 1/4, 1, 1/2, 3/4 ) wavelength = ( 3/2n, 2n, 1n, 1/2n ) radians
90 degrees = ( 1, 3/4, 1/4, 1/2 ) wavelength = ( 1/2n, 2n, 3/2n, 1n ) radians
270 degrees = ( 1/2, 1, 3/4, 1/4 ) wavelengths = ( 3/2n, 1n, 2n, 1/2n ) radians

How to standing waves form?
A wave is and ,

1

A node is

1

An antinode is

1

What is the distance between the nodes for a standing waves?

1

Diffraction is

1

What does s diffraction pattern of laser light passing through a slit look like?

1

What happens to the size and brightness of the spots if you use a smaller diffraction grating?

1

When the wave displacements add to make a larger displacement we call it ( constructive interference, destructive interference ). When they add and cancel out to make zero displacement we call it ( constructive interference, destructive interference ).

1

The phase difference when 2 waves are exactly in step is and the path difference is wavelengths
When in antiphase the phase difference is and the path difference is

1

Sources of waves are said to be coherent when they have , and

1

Path difference is by 2 waves arriving

1

What is the refractive index?

1

The formula for Snell's Law is

1

The critical angle is exits , greater than this causes

1

Polarisation is when occur

1

The electrons are emitted instantaneously because has energy greater where as if it were a wave then to the work function so there would be
