Question

A source produces 15 crests and 15 troughs in 3 sec. when the second crest is produced,the first is 2cm away from the source.Calculate the wavelength. explain how it is calculated

Answer 1

Explanation:

Given A source produces 15 crests and 15 troughs in 3 sec. when the second crest is produced,the first is 2 cm away from the source.Calculate the wavelength. explain how it is calculated

• We know that time period T = 1 / frequency.
• Given wavelength = 2 cm
• Number of waves produced / sec = frequency = 15 / 3 = 5 herrtz.
• Now speed of the wave = frequency x wavelength
•                                     = 5 x 2  
•                                  = 10 cm / sec
