wave
It is able to pass energy from each surrounding of it, as a recurring event.
1 of 23
wavelength
It is the measurement of a distance between two identical peaks (high points) or troughs (low points) in a wave, a repeating pattern of travelling energy like light or sound that has been shown.
2 of 23
frequency
The frequency is shown as the number of cycles per second in an alternating current of direction. The standard unit of frequency can be shown as in hertz.
3 of 23
amplitude
It is the maximum displacement of points on a wave where the degree of intensity that has been changed.
4 of 23
oscillation
This can be shown as the periodic motion that repeats itself in a regular cycle. An oscillating movement being formed around an equilibrium point or a mean value.
5 of 23
transmission
It can be shown as waves passing through and object.
6 of 23
Stationary wave
They are defined as a result of the superposition of two waves with the same amplitude and frequency, travelling at the same speed, but in opposite directions.
7 of 23
Diffraction grating
A diffraction grating can be defined as a flat plane object that has a series of regular lines which have been formed on the block parts of an advancing wave - front.
8 of 23
superposition
This ca be defined as waves being added together when being shown in separate sources that have been overlapped at a given location in space.
9 of 23
Path difference
It is defined as the difference in length between two straight lines from a particular grating to a given point in space from the next grating gap.
10 of 23
coherant
This can be defined as the waves have a constant phase difference and the same frequency, and the same waveform.

Interference pattern
Wave interference is a phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the

resonance
Resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies.

Applications of stationary waves
Radio and TV antennas have a reflector element that bounces the incoming waves which creates a stationary pattern. In microwave ovens, stationary wave patterns are caused by reflections from the metal sides of the oven, creating a lot of hot and cold spot

Fringes
In a double slit experiment, where you can see the two sets of diffracted waves interfere with one another and form an interference pattern. This can be seen on the screen where there are patterns of bright and dark bands known as fringes. The brighter ba

Refractive index:
This is defined as the transparent medium in the ratio of the speed of light in a vacuum to the speed in a medium.
16 of 23
Normal line
This is the line at right angles to the surface of a transparent medium that passes through the point where a ray enters and exits that medium.
17 of 23
incedence
It is shown as the direction of the incoming ray.
18 of 23
refraction
It can be defined as the bending of the direction of travel, so it describes the travel of an outgoing ray after bending.
19 of 23
internal reflection
This is a wave that is already in a optically dense medium when it hits the boundary with a less dense medium and the energy reflected back is even more denser.
20 of 23
critical angle
This is a ray with a higher refractive index that is hitting the boundary with a less dense medium and this is the angle of the incidence where the refracted ray would be travelling along the boundary.
21 of 23
Total Internal Reflection
This can be defined as the wave energy is internally reflected, none is lost as being a refracted ray and this happens to angles of incidence larger than the critical angle.

fibre optics (medicine)
Fibre optics are widely used in endoscopes where they are used in keyhole surgery and this is to guide the use of surgical equipment. Light is being piped in from a source outside the body using a small bundle of optical fibres where the image from inside
