Understanding Waves and Their Properties

What is the term used to describe the number of waves that pass a fixed point in one second?

• Wavelength

• Frequency

• Amplitude

• Speed

Which of the following is the formula to calculate the speed of a wave?

• Speed = Frequency × Wavelength

• Speed = Wavelength ÷ Frequency

• Speed = Frequency + Wavelength

• Speed = Frequency - Wavelength

If a wave has a frequency of 10 Hz and a wavelength of 2 meters, what is its speed?

• 5 m/s

• 10 m/s

• 20 m/s

• 30 m/s

What is the unit of measurement for frequency?

• Meters

• Seconds

• Hertz

• Joules

A wave travels at a speed of 300 m/s and has a frequency of 50 Hz. What is its wavelength?

• 6 m

• 5 m

• 4 m

• 3 m

Which of the following best describes wavelength?

• The height of a wave

• The distance between two consecutive crests or troughs

• The number of waves passing a point per second

• The speed at which a wave travels

If the wavelength of a wave is doubled while the speed remains constant, what happens to the frequency?

• It doubles

• It remains the same

• It is halved

• It quadruples

What is the speed of a wave with a frequency of 25 Hz and a wavelength of 4 meters?

• 50 m/s

• 75 m/s

• 100 m/s

• 125 m/s

Which of the following factors does not affect the speed of a wave?

• Medium through which it travels

• Frequency

• Wavelength

• Amplitude

A wave has a speed of 340 m/s and a wavelength of 0.85 meters. What is its frequency?

• 200 Hz

• 300 Hz

• 400 Hz

• 500 Hz
