Wave Parts
What is the top point of a wave called?
The Crest
Does a Microwave produce Infrared Waves?
No
How much light does a transparent material let through?
Almost all light passes through
What is the Iris and what is its function?
The Iris is the colored part of the eye and controls the amount of light that comes in by changing the size of the pupil
What 3 bones inside your body vibrate to make the hairs in your Cochlea move?
The Hammer, Anvil, and Stirrup
What wave has vibrations perpendicular to the direction of travel?
Transverse Wave
True or False: All EM waves are Transverse waves
True
How much light does translucent material let through?
About some of the light passes through
What are the Lens and what is its function?
The Lens are the clear part of the eye right behind the Pupil that reflects the light on the back of the eye to make an upside-down image
What is the Pinna and what is its function?
The Pinna is the outside part of the Ear and its job is to funnel the sound into the Ear Canal
What wave has compressions and rarefactions in it? Also it vibrates parallel to the direction of travel.
Longitudinal Wave
Which wave has the highest frequency?
Gamma Rays
How much light does opaque material let through?
Almost none gets through
What is the Retina and what is its function?
The Retina is the back part of the eye that has special cells known as rods and cones that detect color and dark color. It also makes sense of the image and sends electric signals to the Optic Nerve to send to the Brain
What is the Ear Canal and what is its function?
The Ear Canal is a passageway that leads to the Eardrum so it will vibrate to the sound
What is Amplitude?
The measurement from the rest position to the crest
What wave has the least frequency?
Radio Waves
If light is reflected, what happens?
The light is reflected at the angle it hit the surface
What is the Cornea and what is its function?
It is the clear, thin lining in front of the Pupil/Iris to protect them and the rest of the eye
What is the Eardrum and what is its function?
The Eardrum is in the Ear Canal and it vibrates to the sound so the Hammer, Anvil, and Stirrup will vibrate the Cochlea
What is frequency?
The rate of waves per second that pass a certain point
What are Gamma Rays used for in the Medical Field?
They use in the Medical Field by treating tumours and Cancer.
If light is refracted, what happened?
The light is bended as it enters the object or medium and changes it´s speed
True or False: Cones see color light and white light while Rods see low level light and black light
True
What is the Cochlea and what is its function?
The Cochlea is the shell-shaped part of the ear and has hairs that vibrate to send electric impulses to the Auditory Nerve
