आइंस्टीन के $E = mc^2$ समीकरण में $c$ द्योतक है-
In Einstein's equation $E = mc^2$, $c$ denotes-
SELECT CORRECT OPTION:
A
ध्वनि वेग का
Speed of sound
B
प्रकाश गति का
Speed of light
Correct
C
प्रकाश तरंगदैर्ध्य का
Wavelength of light
D
एक स्थिरांक
A constant
Official Solution & Explanation:
Correct Answer: Option B(प्रकाश गति का)
आइंस्टीन ने प्रदर्शित किया है कि द्रव्यमान ऊर्जा के समतुल्य होता है। आइंस्टीन के सूत्र के अनुसार- $E = mc^2$, जहाँ $E$ = ऊर्जा, $m$ = द्रव्यमान तथा $c$ = निर्वात में प्रकाश की गति (लगभग $3 \times 10^8\text{ m/s}$) है।
Einstein showed that mass and energy are equivalent according to the equation $E = mc^2$, where $E$ is energy, $m$ is mass, and $c$ represents the speed of light in vacuum (approximately $3 \times 10^8\text{ m/s}$).
