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

Which of the following electromagnetic waves has the lowest frequency?

• gamma ray

• infrared wave

• visible light wave

• microwave

Which is true about the speed of radio waves compared to light waves? They are...

• less energy & frequency, but still the SAME speed as the speed of light (300,000,000 m/s)

• less energy & frequency, so LESS than the speed of light (300,000,000 m/s)

• smaller wavelength, so LESS than the speed of light (300,000,000 m/s)

• more energy & frequency, so MORE than the speed of light (300,000,000 m/s)

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern

High frequency in EM waves equals

• high energy and short wavelength

• high energy and long wavelength

• low energy and short wavelength

• low energy and long wavelength
