Understanding Frequency and Period in Waves

What does frequency describe in the context of waves?

• The distance a wave covers

• The number of cycles per unit of time

• The amplitude of a wave

• The speed at which a wave travels

Which of the following is an example of a periodic event?

• A pendulum swinging

• A person walking

• A car accelerating

• A leaf falling from a tree

How is the period of a wave defined?

• The distance between two crests

• The amplitude of the wave

• The speed of the wave

• The time taken for one complete cycle

What is the relationship between frequency and period?

• They are inverses of each other

• They are unrelated

• They are directly proportional

• They are the same

If a wave has a frequency of 5 Hz, what is its period?

• 1 second

• 5 seconds

• 0.5 seconds

• 0.2 seconds

Which statement is true about frequency and speed?

• Frequency describes how fast a wave moves

• Frequency and speed are the same

• Frequency describes how often a wave occurs

• Frequency is always greater than speed

What is the frequency of a tuning fork vibrating at 300 cycles per second?

• 300 seconds

• 300 Hertz

• 300 meters per second

• 300 cycles

In the example problem, what is the frequency if a wave machine completes 150 cycles in 30 seconds?

• 3 Hertz

• 5 Hertz

• 15 Hertz

• 10 Hertz

How do you calculate the period if you know the frequency?

• Add the frequency to time

• Subtract the frequency from time

• Divide 1 by the frequency

• Multiply the frequency by time

What is the period of a fly flapping its wings 500 times in 5 seconds?

• 0.01 seconds

• 10 seconds

• 0.1 seconds

• 1 second
