Find the propagation velocity of a wave of wavelength 7.50 m . find the period t for a wave of wavelength 7.50 m . on the east coast of the united states, the national weather service frequently reports waves with a period of 3.92 s . find the wavelength of these waves

velocity = 3.42 m/s

T = 2.19 s

wavelength = 0.4056 m

Explanation:

given data

wavelength λ = 7.50 m

to find out

velocity , period T and wavelength when time 3.92 s

solution

we will apply first velocity formula that is

velocity =   ..............1

put here all value g = 9.8, wavelength = 7.50

velocity =  

velocity = 3.42 m/s

and

time formula that is

velocity = wavelength × f     ..............2

here f is frequency = 1/T       .............3

so

velocity = wavelength × 1/T    ..............4

T =

T =

T = 2.19 s

and

wavelength by time 3.92

relation between wavelength and time is express as

T =    .............4

so

3.92 =

3.92 =

6.076 × wavelength = √wavelength

√wavelength = 1 / 6.076

wavelength = 0.4056 m

newton's first law of motion

the answer is a 3.8cm
