The distance between two successive crests of a water is 1m. lf a particle on the surface of the water makes two complete vertical oscillations in 1 second, calculate the speed of the wave

2 complete oscillation in 1s
1 complete oscillation will be 0.5(i.e T)
F =1/T = 2
Wavelength= 1
v=F×wavelenght = 1×2 = 2ms-¹

v=wavelength ×frequency=1×2=2m/s=C

V=f*lands.to find the frequency, f=oscillation/time=2/1=2HZ.to find the speed=f*lands=2*1=2m/s ans

The answer is wrong! F = oscillation/time, so F = 2/1 = 2. Lamda = 1m. Speed = F x lamda = 2 x 1 = 2m/s.

nop..ans is 0.5..

T=t/n....2/1..=2sec...since T=1/f,den...f=1/2=0.5...v=f*lamda=0.5*1=0.5..."A"

---Data--

λ=1m
f=1 complete oscillation=360° or 2π

so 2 complete oscillations=720° or 4π rad/sec

soln

V=fλ
V=4π m/s
