The phenomenon of polarization of light demonstrates that light is a:
Correct Answer: Option D
Explanation:
Polarization (restriction of electric field oscillation to one plane) is possible only for transverse waves, where oscillations are perpendicular to propagation direction. Longitudinal waves (e.g., sound) cannot be polarized as oscillations are along propagation. This was key evidence for light's transverse wave nature. Memory aid: 'Polarization ⇒ transverse wave; light is EM transverse wave'. This conceptual question tests wave optics fundamentals, frequently examined in competitive exams. Always distinguish wave types: transverse (light, string waves) vs longitudinal (sound, spring waves).

SONAR is based on the principle of:
Correct Answer: Option D
Explanation:
SONAR (Sound Navigation and Ranging) relies on the reflection of ultrasonic waves. A transmitter sends out sound waves, which travel through water, strike an object (like a submarine or the seabed), and reflect back as an echo to a receiver. By measuring the time taken for the echo to return, the distance can be calculated.
