Wave speed
v = fλ
Where: f = frequency (Hz) / focal length (m), λ = wavelength (m) / decay constant, v = final velocity / speed (m/s)
Solved example
Given: f = 7, lamda = 5
Find: v (final velocity / speed (m/s))
- Formula: v = f·λ
- Substitute the values: v = 5·7
- Result: v = 35 m/s
Answer: v = 35 m/s

Frequently asked questions
What is the formula for Wave speed?
The formula is v = fλ, where f = frequency (Hz) / focal length (m), λ = wavelength (m) / decay constant, v = final velocity / speed (m/s).
What is Wave speed when f = 7, lamda = 5?
v = 35 m/s. Substitute the values into v = fλ and simplify.
