Sounds waves are waves that need a medium to travel through. These waves are longitudinal where the sound will travel through so that we can hear.
These waves will travel through and hit other particals until it reaches your ear. The particals that hit each other will move back to its original place.
-
Light waves are waves that don't need a medium to travel through. These waves are called transverse the transverse waves will move up and down passing the energy for light to be seen.

The ear drum is a very sensitive part of your ear so if the sounds waves are vibrating the ear drum will also vibrate.
The sounds wave will reach the ossicles the ossicles contains 3 bones the malleus, incus and the stapes. These 3 bones job is to increase the sounds waves so that it can travel through the cochlea.
The waves will increase before it reaches the cochlea because the cochlea has water in it not air so it's harder for them to travel through water than air.

A medium is something sound needs to travel with. Without a medium sound cannot travel. Places without a medium is called a vacuum
-
A reflection is something that bounce. Example, if you reflect a light at the window it will reflect back leaving only a bit of light passing through.

The pupil is a black dot in the middle of the eye which helps collect as much light when it's dark. When it's dark the pupil opens out but when it's bright the pupil becomes smaller.

The retina is at the back of our eye which has many cells. These cells are cone cells and rod cells. The cone cells are used to process colors and the rob cells are used to process black and white.
Echo is something that bonces back aganist the walls. Example, if you say something is a small room the sound will bonce creating the same words you say to repeat until it fades.
Seismometer is a device that measures how big an earthqauke is. During an earthquake this device can detect that earthquake and how big it is.
Interference is when something joined together which can create something to destruct or create something to become bigger.
Constructive interference is when two waves joined together to create a bigger wave. Constructive interference is also the opposite of destructive interference.
Destructive interference are waves that joined each other that creates a smaller wave or cancels out the wave.
-
Electromagnetic spectrum are waves that don't need a medium to travel like lights waves, radio waves, x - rays, microwaves and more.

Frequency is how full a wave is in the time period if the waves are more squezed together you can tell that there is a higher frequency. To measure frequency it's, F= 1/ time, so it's speed of the wave divided by the wavelength.
Time period is to measure how long something like if you are measuring how many seconds it take to measure a full wave that is a time period.
Wavelength is how far one wave is from the other like if wave 1 is 2 blocks away from wave 2 the wavelength is 2 blocks.
