Question:
A source emits electromagnetic waves of wavelength 3 m. One beam reaches the observer directly and other after reflection from a water surface, travelling 1.5 m extra distance and with intensity reduced to \(\frac 14\) as compared to intensity due to the direct beam alone. The resultant intensity will be
