1.	Statement I : In standing waves on a string , the medium particles , i.e., different striung elements remain at rest . Statement II : In standing waves all the medium particles attain maximum velocity twice in one cycle.A. Statement I is true , Statement II is true , Statement II is a correct explanation for Statement I.B. Statement I is true , Statement II is true , Statement II is NOT a correct explanation for Statement I.C. Statement I is true , Statement II is false.D. Statement I : is false , Statement II is true.
Answer» Correct Answer - D In standing waves the medium particles are oscillating and hence are not at rest , though few particles present at the location of node remain at rest.
