Electromagnetic Waves

As wavelength increases, frequency decreases, with frequency decreasing, energy increases.

• True

• False

• Insufficient data

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 particles)

• EM waves can change direction by reflection
