Question

(1) A wire of length 80 cm has a frequency of 256 Hz. Calculate the length of a similar wire under similar tension.
which will have frequency 1024 Hz.
ii) A certain sound has a frequency of 256 Hz and a wavelength of 1.3 m.
1. Calculate the speed with which this sound travels
2. What difference would be felt by a listener between the above sound and another sound travelling at the same
speed, but of wavelength 2.6 m?​

Answer 1

Answer:

Explanation:

1. 1,235 km/h

    The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.
