What is the speed of a wave with a wavelength of 3 m and a frequency of .1 hz? 0.03 m/s 0.3 m/s 3.1 m/s 30 m/s

The correct answer is option b, 0.3m/s

Step by Step solution:

The relation between speed, wavelength and frequency of a wave is given by the following equation:  

Speed = Wavelength x Frequency

Substituting the values in above equation we get –  

= 3  x 0.1  

= 0.3 m/s  

it has one origin of replication, but it proceeds in two directions - d)
