Question 1
A sound wave in air at 25 degrees Celsius travels at a speed of about 346 m/s. If the temperature increases to 35 degrees Celsius, what will be the new speed of sound?
💡 Hint: Alter T in the formula to reflect the new temperature.
Question 2
Two sound waves meet: one with a frequency of 400 Hz and another with 600 Hz. What is the effect of their interference at the point where they meet?
💡 Hint: Consider phase alignment in wave characteristics.
