Question

10. The pitch of a sound wave and the color of a light wave are characteristics of A) period B) wavelength C) amplitude D) none of these 12. In which one of these media does sound travel faster? A) gas B)liquid C) solid D) Sound travels at the same speed in all of them Work the following problems on your own paper. 1. A sound wave has a frequency of 255 hertz. If the sound waves are 1.35m in length, what is the speed of sound? B. What is the period? 2. The speed of a radio wave is 3.00 x10 m/s. If the radio wave is 94.3 am long, what is the frequency of the wave? 3. The speed of a sound wave in water is 1,497 m/s. If the sound wave has a frequency of 1.25ke what is the wavelength of the sound? What is the speed of a wave (in m/s) if the wave has a frequency of 220 Ht and a wavelength of 25nm? (watch units)

Explanation / Answer

The pitch of a sound wave is measured as frequency. Again the frequency has relation with wavelength. Therefore, in other way, Pitch is characterestic of wavelength.

It is well known that the color of the light depends on it's wavelength.

SO, the pitch of the sound waves and color of the light waves are characteristics of Wave length
