Question

What is the u of the wave if λ = 10 m?
You must use the GUESS process to show work and receive points.
Given
Unknown
Equation
Substitution

Answer 1

I can, but I need one more piece of information. Use GUESS (Given, Unknown, Equation, Substitution, Solution) as requested:

G: Given
- λ = 10 m
- (no frequency or other info supplied)

U: Unknown
- u (wave speed)

E: Equation
- For a travelling wave, wave speed u = λ · f (where f is frequency).
- (If this is a wave on a string and you instead know tension T and linear mass density μ, use u = sqrt(T/μ).)

S: Substitution
- Using u = λ f: u = (10 m) · f = 10 f (m/s)

S: Solution
- Without f you can only give u in terms of f: u = 10 f m/s.
- Example: if f = 2 Hz, u = 10·2 = 20 m/s.

If you tell me the frequency f (or T and μ for a string), I will compute the numeric value of u.
