A) 100 cm
B) 5 cm
C) 3 cm
D) 2 cm
Correct Answer: D
Solution :
The equation is given \[y=3\cos \pi (100t-x)\] ...(1) The standard equation of wave is \[y=a\cos \left( \omega t-\frac{2\pi }{\lambda }x \right)\] ?(2) Comparing the given equation (1) to standard equation (2) we get \[\frac{2\pi }{\lambda }=\pi \] or \[\lambda =2cm\]You need to login to perform this action.
