Question 1.
What does T represent in the wave equation?
Show hintHide hint
Think about what keeps the string tight.
Question 2.
What is the formula for wave speed?
Show hintHide hint
It relates tension and mass per length.
3Question 3.
What does the wave equation describe?
- Propagation of heat
- Propagation of waves
- Propagation of light
Show hintHide hint
Think about different types of equations in physics.
4Question 4.
True or False: Increasing mass per unit length decreases wave speed.
- True
- False
Show hintHide hint
Relate back to the formula of wave speed.
Question 5.
A string is stretched with a tension of 80 N and has a mass per unit length of 0.04 kg/m. Calculate the wave speed and the fundamental frequency if the string length is 1 m.
Show hintHide hint
Calculate wave speed first, then use it to find frequency.
Question 6.
For a uniform string under tension varying from 10 N to 80 N, analyze how wave speed varies and describe the relationship.
Show hintHide hint
Refer back to the formulas we've learned to link tension to wave speed.
