Answer 1

I’m missing what the symbol "^" stands for and whether u means the wave speed. Can you confirm? (Commonly "^" could be λ, the wavelength, and u is the wave speed.)

I’ll show the GUESS process for the usual case where λ = 10 m and we want the wave speed u.

G — Given
- λ = 10 m
- (need either frequency f or period T to find u)

U — Unknown
- u (wave speed)

E — Equation
- u = f · λ (or equivalently u = λ / T)

S — Substitution
- If you have f, substitute it: u = f × 10 m.
- If you have T, substitute it: u = 10 m / T.

Since you didn’t give f or T, I can’t compute a numeric u. Example: if f = 2.0 Hz then
u = 2.0 Hz × 10 m = 20 m/s.

Give me the frequency f (or period T) and I’ll finish the calculation.
