What is frequency?
Q: What is frequency?
A: Frequency is how often an event repeats itself over a set amount of time.
Q: What unit is used to measure frequency?
A: Hertz (symbol Hz) is the unit of frequency.
Q: What formula expresses the relationship between frequency and wavelength?
A: The relationship between frequency and wavelength is expressed by the formula f=v/λ, where v is speed and λ (lambda) is wavelength.
Q: How does this formula change for light waves?
A: The formula for the frequency of light waves is f=c/λ, where c is the speed of light.
Q: How fast do electromagnetic waves travel in a vacuum?
A: All electromagnetic waves travel at the speed of light in a vacuum.
Q: How fast do they travel through other mediums?
A: Electromagnetic waves travel at slower speeds when they travel through a medium that is not a vacuum.
Q: Are there any examples of electromagnetic waves?
A: Examples of electromagnetic waves are light waves, radio waves, infrared radiation, microwaves, and gamma rays.
