Waves
This type of wave cannot travel in a vacuum.
What is a sound wave.
What type of wave is a sound wave?
What is longitudinal wave.
If a light wave changes speed when it passes from one medium to the next this will happen to the light ray.
What is refraction.
These are the receptors in the retina that are responsible for color.
What are cones.
This type of electromagnetic radiation has the LONGEST wavelength.
What are radio waves.
This is the measurement of how many waves pass a point in a certain amount of time.
what is frequency.
What behavior of a waves explains the production of an echo?
What is reflection
This term refers to the straight path that light travels.
what is a ray
This area of the ear is responsible for funneling this sound.
What is the outer ear.
Cell phones use this type of radiation.
What are radio waves.
This is the highest point of a wave.
what is crest
Sound travels fastest in what kind of material?
What is a solid.
The name of the imaginary line drawn perpendicular to the surface that a light wave strikes.
What is the normal line.
This area of the ear converts signals from the middle ear and sends the signal to the brain
What is the inner ear.
As the frequency of a wave increases this happens to the wavelength.
This type of light transmission describes an object that allows light to pass through and shows a clear image.
What is transparent.
This refers to how high or low a sound is.
What is pitch
This type of mirror will form an upside down image if the object is placed behind the focus point.
This part of the eye allows light to enter.
What is the pupil.
What section of the EM spectrum is visible to the human eye.
What is visible light
This type of signal is a more reliable way to send and store information.
What is digital signal
These are areas on a longitudinal wave where the air particles are close together
What is compression
This law states that the angle of incident will equal the angle of reflection.
what is the law of reflection.
These are the receptors in the eye that are allow humans to see light.
What are rods.
