Question

In the lab, you will be creating shallow water waves with a "ripple" generator. When you attach a long horizontal rod to the generator it makes plane waves that behave much like waves on a string (see chapter 15). The speed of the waves in the ripple tank depends on the depth of the water layer. In the lab, you will measure the wavelength of the plane waves for different frequencies at the same depth of the water. When you double the frequency you expect the wavelength to become half as large as before. stay the same. become four time as large as before. become twice as large as before. Save The bending of waves around an obstacle is called diffraction. interference. coherence. superposition.

Explanation / Answer

as V = Lf

where L is wavelength

f is frequnecy

since V remians same in that medum

changing f ( doubleing) wil reduced the waveength by factor of 2

so option A:

--------------------------------------------------

the bending of waves around an obstacle is called Diffraction

option A
