Question

What you understand by the term Wavelength. Calculate the Frequency and Time Period
of a radio wave having its wavelength of 10m propagating in space.

Answer 1

Ans : Wavelength = Velocity / Frequency

                                   Frequency= velocity / wavelength

                                   Time period = 1/Frequency

         

Explanation:

Wavelength is the distance between Two Corresponding point on adjacent waves.

Wavelength of radiowave = 10m

Then, Frequency= velocity / wavelength                   (C=speed of light )

                                 =  3*108  /10                                        ( C=3*108)

                                  =  3*107Hz

                     Time Period=1/Frequency

                                           = 1/3*107

                                          = 0.3*107

Answer 2

Answer:

Wavelength refers to the spatial period of a periodic wave.

Frequency is $3*10^{7} Hz$

Time period is $0.3*10^{-7} s$

Explanation:

Wavelength: It is defined as the distance between two successive crests or troughs of a wave.

It is calculated in the direction of the wave.

Mathematically,

Frequency= velocity/wavelength

Time period is inverse of frequency.

Time Period=1/Frequency

We are given wavelength $10m$

Frequency =$\frac{3*10^{8} }{10}$

$=3*10^{7} Hz$

Time period $=\frac{1}{3*10^{7} }$

$=3*10^{-7} s$
