Longitudinal Waves
Which electromagnetic waves allow us to treat cancer?
Which has the LONGEST wavelength and, therefore, the lowest frequency and lowest energy?
Which has the SHORTEST wavelength and, therefore, the highest frequency and highest energy?

How are Electromagnetic waves different from Mechanical waves?
EM waves have very short wavelengths
EM waves transmit energy instead of matter
EM waves can travel through the vacuum of space (without a medium)
EM waves can change direction by reflection
A wave has wavelength of 10 m and a speed of 340 m/s. What is the frequency of the wave?
Speed = Wavelength x Frequency
