Explanation:

Statement 1 is accurate as SARAS 3 is a precision radio telescope designed to detect very faint radio wave signals.

Statement 2 is incorrect. Radio waves have longer wavelengths and, consequently, lower energy when compared to other waves like gamma rays, X-rays, or even visible light. The energy of a wave is inversely proportional to its wavelength, meaning longer wavelengths have lower energy.
