Sonar is a device that uses reflected sound waves to measure underwater depths. If a sonar signal has a frequency of 288 Hz, and the wavelength is 5.00 m, what is the speed of the sonar signal in water?

Given that,

The frequency of a sonar signal, f = 288 Hz

Wavelength = 5 m

To find,

The speed of the sonar signal in water.

Solution,

Let the speed of the sonar signal is v. The speed in terms of wavelength and frequency is given by :

So, the speed of the sonar signal in water is 1440 m/s.

it has to be b, about 97 percent.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
