Waves and EMS

Why do scientists use models?

• to represent something too small to see

• to represent something too large to study

• to represent something too dangerous to study

• all of these

The height of the wave from baseline to crest (or trough) is called the:

• amplitude

• wavelength

• frequency

• wave period

Which of these would affect the SPEED of a wave?

• None of these

• Change in wave amplitude

• Change of wave frequency

• Change in the medium wave travels through

What is the relationship between the frequency and energy of a wave?

• Low frequency and high energy

• Frequency does not affect energy

• High frequency and high energy

• High frequency and low energy

The number of waves that pass a given point in a certain time is called the:

• wavelength

• frequency

• amplitude

• wave time period

What property do light and sound waves share?

• they carry energy

• they have the same frequency

• they travel through any form of matter

• they travel through the vacuum of space
