The Wave Equation (v=fλ) | GCSE Physics Practice

Calculate the speed of any wave using its frequency and wavelength.

If velocity is constant, how does frequency relate to wavelength?

What is The Wave Equation (v=fλ) | Practice?

"The relationship between wave speed, frequency, and wavelength: $v = f lambda$."

Question 1

Which of these is an example of a longitudinal wave?

Question 2

If an object absorbs more radiation than it emits, its temperature will ____.

Question 3

Arrange these EM waves in order of INCREASING energy: Radio, Visible, UV, Gamma.

Question 4

The distance between the same point on two adjacent waves is called the ____.

Standard Formulas

Wave speed (m/s) = Frequency (Hz) x Wavelength (m).

The speed of all EM waves in vacuum is $3 imes 10^8$ m/s.

Frequency is the number of waves passing a point per second.

Wavelength is the distance between two consecutive peaks.

Exam Tip

Prefix Alert: Exams often give frequency in kHz or MHz. Remember: 1 kHz = 1,000 Hz, 1 MHz = 1,000,000 Hz.

Want to improve faster?

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
