Grade 8 gradeScience subjectFree quiz

Grade 8 waves cover mechanical waves in matter and electromagnetic waves that can travel through space. Students relate speed, frequency, and wavelength by v = fλ, compare transverse and longitudinal motion, and place radio through gamma rays on the electromagnetic spectrum. Amplitude is linked to intensity, not to wave speed in a given medium.

What you practice

These are the Grade 8 Waves & EM Spectrum skills this quiz is built around.

Use v = fλ to find speed, frequency, or wavelength when two of the three are known.
Classify a wave as transverse or longitudinal from the direction of particle motion.
Order common electromagnetic waves by wavelength or energy.

A useful tip

In one medium, raising frequency shortens wavelength because speed stays about the same. Treating speed as if it rose with frequency is a common mix-up.
