Elijah and Samuel are at the beach, watching the waves. If one wave has a frequency of 10 Hz and a wavelength of 2 metres, can you help them figure out its speed?

• 5 m/s

• 10 m/s

• 20 m/s

• 40 m/s

Nora and Grace are at the beach, watching the waves. Nora asks, "Hey Grace, do you know what equation we can use to find the speed of these waves?"

• speed = frequency x wavelength

• speed = hertz x frequency

Observe the model of a light wave moving from the air to a solid. What do you notice changed about the wave?

• The wavelength of the light wave increased.

• The speed of the wave increased when it moved to the solid.

• There was no change in the wave.

• The speed of the light wave decreased.
