Question

State two ways of increasing frequency of vibration of a stretched string.​

Answer 1

Answer:

The frequency of vibration of the stretched string can be increased by increasing the tension in the string, by decreasing the length of the string.

Answer 2

$\underline{\bigstar{\underline{\pmb{\sf{\red{Ways \;of\; increasing\; frequency\; of \;vibration \;of\; a\; stretched \;string\;:}}}}}}$

• ↠ By increasing tension of string.
• ↠ By reducing the radius of string.

$\;\;$

$\qquad\qquad\boxed{\underline{\underline{\purple{\bigstar \:\bf\:More\:to\:know\:\bigstar}}}}$

• » Frequency (F) is inversely proportional to radius.

• » Frequency (F) is directly proportional to ‘√’ of tension.

• ↪ Frequency is the number of waves that påss a fixed point in unit time.

• ↪ An "A" note on a violin string vibrates at about 440 Hz.
