प्रकाशाचा वेग ____________ असतो. Speed of light is ____________.
1)3×10⁸ मीटर प्रतिसेकंद / 3×10⁸ m/s✓ Correct
2)3×10⁸ सेंटीमीटर प्रतिसेकंद / 3×10⁸ cm/s
3)3×10⁸ किलोमीटर प्रतिसेकंद / 3×10⁸ km/s
4)3×10⁸ इंच प्रतिसेकंद / 3×10⁸ inch/s
The speed of light in a vacuum is a fundamental physical constant, approximately equal to 3 × 10⁸ meters per second.
प्रकाश तरंग मुख्यत: ____________ स्वरूपात असतात. Light is generally in the form of :
1)चुंबकीय तरंग / Magnetic Waves
2)विद्युत तरंग / Electrical Waves
3)विद्युत चुंबकीय तरंग / Electromagnetic Waves✓ Correct
4)वरीलपैकी एकही नाही / None of the above
Light travels in the form of electromagnetic waves, specifically transverse waves.
रेडिओ तरंगाचा वेग हा ________ असतो. The velocity of radio waves is ________
1)प्रकाशाच्या वेगापेक्षा जास्त / Greater than velocity of light
2)प्रकाशाच्या वेगा एवढाच / As that of velocity of light✓ Correct
3)प्रकाशाच्या वेगापेक्षा कमी / Less than velocity of light
4)प्रकाशाच्या वेगाच्या दोन पट / Exactly double the velocity of light
Radio waves are electromagnetic waves. All electromagnetic waves travel through a vacuum at the speed of light (approximately 3 × 10⁸ m/s).
