Statement A: Sharp edge of a fine needle doesn't cast clear shadow.

Statement B: Sharp edge of needle capable to diffract radio wave.

View answer and explanation

Correct option: C

A is correct and B is wrong

Option C (A is correct and B is wrong) is correct because sharp edges of fine needles do not cast clear shadows due to diffraction, but needles are not capable of diffracting radio waves because radio waves have much larger wavelengths.
