A wave has a wavelength of 6 mm and a frequency of 9 hertz. What is its speed? what is the answer and units?
1 answer:
Answer:The speed is 54 mm/s, the units are mm/s.
Explanation:
1) Data:
a) λ = 6mm
b) f = 9 Hz = 9 s⁻¹
c) v = ?
2) Formula:
wave equation: v = f × λ
3) Solution:
v = 9 s⁻¹ × 6mm
v = 54 mm/s
The speed is 54 mm/s, the units are mm/s.
