IQ REVIEW

What is a medium? Do all waves require a medium? If a wave requires a medium, what type of wave is it? Draw a wave and label the crest and trough What are the the two types of waves?

What are the two parts of a longitudinal wave? Draw a wave, and label crest, trough, amplitude, and wavelength. Define frequency. What is the formula for the speed of a wave?

Assuming the speed of a wave is constant: What would happen if the wavelength decreased? What would happen is the wavelength increased? What is the metric measure for frequency?

What is the Doppler Effect? Where do you most often observe the Doppler effect? How do meteorologists use the Doppler effect? How do astomomers use the Doppler effect

What type of wave is sound: transvers or longitudinal? Is sound a mechanical wave? Why? Will sound travel in a medium? Why? Through which mediums does sound travel faster?

Does sound travel through a solid? Does sound travel through water? What is the relationship between temperature and the speed of sound?

What is an echo? Lesson Review What is a reflection? What animals use echolocation? What has man used echolation for in deep sea exploration? What does the Navy use echolation for? What is Sonar?

In order to use sonar: a ship must be equiped with both a ____ and a _____. What do doctors use sound echos for?

What are the three parts of the ear? What are the three bones of the middle ear? Briefly describe how "waves" enters the ear and turn into sound at the brain. What type of wave is sound? (Transvers or Longitudinal)

Is sound a mechanical wave? Why? Light is a form of what type of energy? Light is made up up of small bundles of energy called? Is light a mechanical wave? Does light always travel in a straight line?

Distinguish between illuminated and luminous Distinguish between opaque, translucent, and transparent? Is the moon a luminous object? What is the clear layer which covers the eye? Where, in the eye, does light first pass through?

Which muscle controls the size of the pupil. Where is the retina located? What is the acronym for visible light? Which color has a longer wavelength: red or blue?

Do radio waves have a short wavelength? Do gamma rays have a low frequency? What size W/L do they have?
