FOSS Waves - Inv. 1

You and your partner created a standing wave. You measure the distance between two adjacent (next to each other) nodes to be 7.5 cm. What is the wavelength of your standing wave?

• 7.5 cm

• 3.75 cm

• 15 inches

• 15 cm

Which wave has the largest frequency?

• A
• B
• C
• None (same frequency)

Bob measures the frequency of a wave as 3 waves/second and the wavelength as 20 cm/wave. Using the velocity equation (v = f  x  $\lambda$ )  what is the speed of the wave?

• 23 cm/sec

• 6.66 cm/sec

• 60 cm/sec

• 60 waves/sec

Which wave has the largest wavelength?

• A
• B
• C
• None (same wavelength)

Longitudinal waves move:

• at a right angle compared to the direction the wave is traveling

• in a circle compared to the direction the wave is traveling

• matter

• in the same direction as the wave is traveling

#4 refers to the

In what type of wave does the motion of the wave travel perpendicular to the energy of the wave?

• surface wave

• compression wave

• transverse wave

• electromagnetic wave

#2 refers to the
