1. (i) wavelength, frequency
(ii) Q, R
(iii) S, T
(iv) P, R
2. (i) H represents a compression, and I represents a rarefaction.
(ii) Letter G represents a wavelength.
3. The frequency of the waggling is 5 Hz.
4. A wave that vibrates perpendicular to the direction of travel of the wave is called a transverse wave.
5. Light waves and electromagnetic waves vibrate perpendicular to the direction of travel.
6. Sound waves contain compressions and rarefactions.
7. Longitudinal waves are produced when one end of a horizontal spring is pushed up and down.
8. Transverse waves have a wavelength.
9. Wavelength = 0.5 m
Parent Tip: Review the logic above to help your child master the concept of transverse and longitudinal waves worksheet.
