Waves
Physics
The order of the electromagnetic spectrum from highest frequency/energy to lowest is: | - Gamma waves (highest) - X rays - Ultra violet waves - Visible light waves - Infra-red waves - Microwaves - Radio waves (lowest) |
What do all the waves listed transfer? | Energy. |
What type of wave are these? | Transverse waves. |
How do all these waves travel? | At the same speed (300,000,000 m/s) through a vacuum. |
These waves can all be...(3 things) | Reflected, refracted & diffracted. |
What is the equation for wave speed? | Wave speed = frequency (f) x wavelength (λ) |
What is MHz called and what does it measure? | Hertz and the unit of frequency. |
How do you work out the wave frequency? | 1 ----------- time period |
