About the ear
100
what is physics?
physics is the study of nature and properties of matter and energy.
100
What does white light consist of?
red, orange, yellow, green, blue, indigo, violet.
100
what are the parts of a wave?
Amplitude, Wavelength, Crest, Trough
100
What are the three primary regions of the human ear?
The outer, Middle and inner
200
what is light?
light is the range of electromagnetic radiation.
200
what are the primary colors in the visible spectrum?
Green, Red, Blue
200
what is a frequency?
frequency if the measure of how many wavelengths pass by in a given time
200
what are the parts of the inner ear?
The cochlea, Auditory nerves and the semicircular canal
300
What is sound made of?
sound is made of waves, of the vibrations passing through a medium (an object)
300
what are prisms used for?
prisms are able to separate white light by slowing sown the light, which changes its direction
300
why does sound travel faster in denser objects?
because the molecules are closer together so vibrations pass more easily
300
Why does wax in the ear affect hearing?
because it prevents vibrations from reaching the ear.
400
what is a ray diagram?
Ray diagrams are used to show the path that light takes in a situation.
400
what happens when light hits an object?
it can either be refracted, reflected or absorbed.
400
What is frequency measured in?
Frequency is measured in hertz (hz)
400
what is the loudness of a sound measured in?
It is measured in decibels (db)
500
What is an oscilloscope?
a machine used to measure sound waves and visualize them on a screen.
500
What are the different wavelengths of light in the electromagnetic spectrum?
Radio, Microwave, Infrared, Visible, Ultraviolet, Gamma
500
what is resonance?
Resonance is when some objects vibrate more at special frequencies.
500
what part of the ear sends a signal to the brain?
The auditory nerve.
