When the source of the waves is moving toward the observer All the waves are pushed closer to the front which creates a high pitch noise. But once the source of the waves moves past the observer the pitch drops because the waves are more spread out at the back. A good example of the Doppler effect is when a vehicle passes you at a fast pace.
Resonance:
resonance is the tendency of a systemCan be used to oscillate with larger amplitudegenerate vibrations at somea specific frequency (e.g. musical instruments), or pick out specific frequencies than at others.from a complex vibration containing many frequencies (e.g. filters).


Visible Light: The EM spectrum as we can see with our eyes, as wavelengths get shorter and shorter, the order goes.
red - orange - yellow - green - blue - violet.
The speed of light = 299 792 458 m / s

Transverse:
Transverse waves are waves that are moving perpendicular to the direction of propagation. If you anchor one end of a ribbon or string and hold the other end in your hand, you can create transverse waves by moving your hand up and down.
Longitudinal:
Longitudinal waves are when the waves vibrate in the same way. which means that the movement of the medium is in the same

Electro-Magnetic waves are produced from the sun and are vacuumed into the earths atmosphere. All light waves are examples of electromagnetic waves.
A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves need a medium to travel around. A sound wave is an example of a mechanical wave.

The Eye:
How we see depends upon the transfer of light. Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.

The Ear:
The external ear consist of two portions, the first being the pinna, the skin covered flabby cartilage of the ear visible on both sides of the head. The basic function of the outer ear or pinna is to protect the eardrum (tympanic membrane). The outer ear also functions to collect sound waves to the eardrum through the ear canal.
The second component of the external ear is the auditory ear canal or meatus. There are modified sweat glands that secrete ear wax in the ear canal. If ear wax is excessive, the ear drum can be damaged or lead to blockage of the transmission of sound.
The middle ear refers to the hollowed air-filled bony space (tympanic cavity) in the temporal bone of the skull behind the eardrum. It is just separated from the outer ear by the ear drum. There are three tiny bones (auditory ossicles) in the tympanic cavity that vibrates when exposed to sound waves, namely.
The inner ear is the most complicated component of the auditory system located into a tiny space of the hardest temporal bone and inaccessible to direct examination or clinical manipulation. The inner ear comprise of three intimately related structures - the cochlea (spiral tube), three semicircular canals and the vestibule (labyrinth).
