Answer:
The wavelength will be 4 cm, frequency will be 4.66 Hz and wave speed is 18.6 cm/sec
Explanation:
Given:
No. of crest = 13
No. of trough = 15
Time = 3 seconds
Hence, 1 crest or 1 trough =
therefore,
13 C + 15 T =
=
Time given 3 seconds
=
2 cm distance is travelled is time period
Again wave will travel in 1 T = 4 cm
wave speed v =
=
= 18.6 cm/s
