Answer:
A Radio has a Frequency of 220 Hertz . The Sound produced by the Wavelength is 4.2 meter . Identify the Speed of the Wave .
11 m/s
0.01 m/s
52.3 m/s
924 m/s
Answer :-
Speed of the Wave is 924 m/s .
Explanation :-
As per the provided information in the given question, we have been given that the Frequency of the Radio is 220 Hertz . Wavelenght is given as 4.2 meter . And, we have been asked to calculate the Speed of the Wave .
For calculating the Speed , we will use the Formula :-
\bigstar \: \: \: \boxed{ \sf{ \: Speed \: = \: Wavelength \: \times \: Frequency \: }}★
Speed=Wavelength×Frequency
Therefore , by Substituting the given values in the above Formula :-
\dag \: \: \: \sf{Speed \: = \: Wavelength \: \times \: Frequency}†Speed=Wavelength×Frequency
\longmapsto \: \: \: \sf{Speed \: = \: 4.2 \: \times \: 220}⟼Speed=4.2×220
\longmapsto \: \: \: \textbf {\textsf {Speed \: = \: 924 }}⟼Speed = 924
Hence :-
Fourth Option is Correct Answer .
