Light is scientifically known as what?
Electromagnetic radiation (EM).
What is a wavelength?
The distance between 2 consecutive troughs or peaks in a wave.
What is frequency?
Number of waves that pass a given point per second.
Frequency (cycles per second) is measured in what unit?
What is amplitude?
Amplitude is the height of the wave as defined by a trough or a peak.
The brightness of light is related to what aspect of it's wave.
True or false. Wavelength and frequency are inversely proportional.
Wavelength times frequency equals what?
c, the speed of light. (3 x 108 m/s)
The wavelength of a light defines it's what?
Blue light has a shorter wavelength than red light or red light has a shorter wavelength than blue light?
Blue light has a shorter wavelength than red light.
What is the equation for wavelength and frequency?
Lambda=wavelength (in meters)
c=speed of light (3 x 10^8)
