Answer 1

We know that:
- Frequency is directly proportional to pitch.
- Time period is directly proportional to the length/size of the instrument.
- Time period is inversely proportional to frequency
(2 Marks)

For a cello:
- Deep sound
- Less frequency
- Less pitch
- More time period (more length)
(1.5 Marks)

For a violin:
- Shrill sound
- More frequency
- More pitch
- Less time period (less length)
