Question 1
Consider a string with mass density ρ = 0.01 kg/m and tension T = 10 N. Calculate the wave speed c and discuss its significance.
💡 Hint: Be sure to plug the values into the wave speed formula correctly.
Question 2
If the tension in the string is doubled while keeping the mass density constant, how does the wave speed change?
💡 Hint: Think about the relationship expressed in the wave speed formula.
