• up
• down
• right

What is the amplitude of this wave?

• 2.0 cm

• 4.0 cm

• 0.7 cm

• 1.0 cm

Answer explanation

The amplitude is from the equilibrium line (middle) to a peak or trough. This is half of the distance from a peak to a trough (2.0 cm in picture).

therefore 2.0/2 = 1.0 cm

What is the wavelength of this wave?

• 2.0 cm

• 0.0875 cm

• 0.7 cm

• 0.175 cm

Answer explanation

The total distance is 0.7 cm. But, there are 4 full waves. So a single wavelength is 0.7 / 4 = 0.175 m
