Waves
What type of wave moves perpendicular to the direction that the energy is traveling?
A Transverse Wave
How many different waves are on the electromagnetic spectrum?
7
What is a crest
the highest part of a Wave
What characteristic of electromagnetic radiation determines what kind of radiation it is?
Its wavelength
Which wave is most commonly used to detect cancer cells and used for cancer treatment?
Gamma Rays
What type of wave moves parallel to the direction that energy is traveling?
Longitudinal Waves
True or False: All EMS waves travel at the speed of sound
False: They travel at the speed of light
What is a trough
the lowest part of a Wave
How do you measure amplitude?
You start from the resting position or equilibrium and measure the distance to eitehr a trough or a crest
what is the longest wavelength on the EM
radiowaves
What is the frequency of a wave
the number of complete waves in a given time period.
what is the shortest wave on the EMS
gamma rays
Hertz
Because they don't need mediums, EMS waves are able to do what?
Travel the vastness of space
What has higher energy x-ray or ultraviolet
xray
the distance from one crest to another, or the distance from one trough to another
Infrared Waves can be felt as what to humans
Heat
longitudinal waves and transverse waves need materials to travel called
mediums
Waves transmit energy from one place to another. Name two properties of waves that affect the energy transmitted by the wave AND describe how each property should change to increase the energy transmitted.
Both the amplitude and frequency can increase the energy of the wave. Increasing the amplitude will increase the energy transmitted by waves. Increasing the frequency will increase the energy transmitted by waves.
What waves are used for sterilizing medical equipment and responsible for cell damage
UV waves
What happens to the wavelength as the frequency increases
the wavelength decreases
What is the order of the electromagnetic spectrum going from highest frequency to lowest
gamma ray, x ray, UV, visible light, infrared, microwave, radio wave
Different types of telescopes, such as gamma ray detectors and radio telescopes, are used in space science. What is the reason for the variety of space-based telescopes?
Different types of telescopes are needed to collect data from different kinds of radiation.
