Question

ln the given figure if a wave in a string, velocity of sound produced is 10 m/s. from from the diagram:

i. find the wavelength.
ii. find amplitude of the wave.
iii. calculate the frequency of the wave.​

Answer 1

Answer:

e

Why lyophobic sols migrate under an applied field and show Tyndall effect whereas lyophilic sols may not, why?

Answer 2

Answer:

wavelength=2m

Amplitude= 4cm

V=freq*wavelength

10m/s= freq*2m

10m/s/2m= 5/s= 5Hz
