Assertion(A) : No diffraction is produced in sound waves near a very small opening. Reason(R) : For diffraction to take place, the aperture of opening should be of same order as wavelength of waves.(a) Both A and R are true and R is the correct explanation of A (b) Both A and R are true but R is NOT the correct explanation of A (c) A is true but R is false (d) A is false and R is also false |
