Doppler's effect is used in sonar and artificial satellites. Therefore, it can be applied toI. light wavesII. sound wavesIII. electromagnetic waves
Correct answer: D. All of these
- A. I only.
- B. III only.
- C. I and II.
- D. All of these
Explanation
I. light waves: Yes, as they are electromagnetic waves and the Doppler effect applies to them (e.g., in astronomy). * II. sound waves: Yes, as demonstrated by sonar and everyday examples like sirens. * III. electromagnetic waves: Yes, as light waves are a part of electromagnetic waves, and applications like radar (using radio waves, another type of EM wave) also utilize the Doppler effect.Therefore, all three types of waves (light, sound, and electromagnetic) are subject to the Doppler effect

About Electromagnetic Waves
Electromagnetic waves consist of mutually perpendicular, oscillating electric and magnetic fields that also remain perpendicular to the direction of propagation. They travel through vacuum at the speed of light and include radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. Unlike mechanical waves, they do not require a material medium.
