Science | EM Waves Flashcards
(blank) is a type of wave that transfers energy.
Electromagnetic Radiation
All waves can be described by their (3 blank).
Amplitude, Frequency, and Wavelength
The height of a wave from its resting point.
Amplitude
Electromagnetic Spectrum
Radio Waves
Microwaves
Infrared Waves
Visible Light
Ultraviolet Light
X-Rays
Gamma Rays
The distance from one peak of a wave to its next peak.
Wavelength
The rate at which how many waves pass a point in a second.
Frequency
Frequency to Wavelength Relationship.
Shorter Wavelength = Higher Frequency
Longer Wavelegth = Lower Frequency
The frequency of waves is also related to the (blank).
Amount of energy they transfer
Electromagnetic waves are created when (blank).
Charged particles move
Waves occur along a spectrum of (blank).
Different wavelengths
Electromagnetic waves are (blank) in nature.
Transverse
They are not deflected by electric and magnetic fields.
Electromagnetic Waves
These waves have long wavelengths that can be the length of a ruler or longer.
Radio waves
It is used to send radio signals, WiFi signals, phone calls, and text messages.
Radio waves
The Sun is the main source of (blank).
Ultraviolet radiation
It is used to study the way different electromagnetic waves interact with matter.
Spectroscopy
(blank) can be detected by our eyes. Light bulbs, stars, etc.
Visible light
It causes skin tanning and burns. Hot materials that are in space also emit this.
Ultraviolet radiation
It has a wide application in the medical field. (blank) imaging is used to see inside our bodies. Interestingly, the universe is the biggest (blank) generator of all.
