E.
wavelength

Answer 1

Answer:

(c) frequency

Explanation:

frequency is the number of waves per second

Answer 2

Frequency can be found by counting the number of troughs per second in a wave diagram

Explanation:

• Wave frequency is the amount of waves that permit a static point in a assumed quantity of time.
• The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second.
• A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
• The definition of frequency is how often something happens. An example of frequency is a person blinking their eyes 47 times in one minute.
