Homework:
2/5 - Copy vocabulary words in NB. Draw wavelength and label it.
1. Intensity - The rate at which a wave's energy flows through a given unit of space
2. Sound wave - A longitudinal wave that is caused by vibrations and that travels through a medium
3. Pitch - A measure of how high or low a sound is perceived to be, depending on the frequency of the sound wave
4. Light Ray - A line in space that matches the direction of the flow of radiant energy
5. Electromagnetic radiation - a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously
6. Electromagnetic spectrum - the range of wavelengths or frequencies over which electromagnetic radiation extends
7. Wavelength and frequency
Light is measured by its wavelength (in nanometers) or frequency (in Hertz).
One wavelength
equals the distance between two successive wave crests or troughs.
Frequency (Hertz)
equals the number of waves that passes a given point per second.
