For years, marine scientist were mystified by sound waves detected by underwater microphones in the pacific ocean. these so-called t waves were among the purest sounds in nature. eventually the researchers traced the source to underwater volcanoes whose rising columns of bubbles resonated like organ pipes. a typical t wave has a frequency of 6.8 hz. knowing that the speed of sound in seawaver is 1,530 m/s, determine the wavelength of a t wave.

225 m

Explanation:

= Frequency of the T wave = 6.8 Hz

= Speed of sound in seawater = 1530 ms⁻¹

= Wavelength of the T wave

we know that, frequency, speed and wavelength are related as

Inserting the values, we get

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
