About This Quiz

The speed of light is considered a constant. It is defined as the speed at which light travels through any material or space. The speed of light through a vacuum has been the center of the universal physical constant that is important in many areas of Physics. Speed through a vacuum is the highest speed at which all matters can travel through the vacuum. Are you aware of the speed of light? Try this quiz.

    What does E stand for in E=mc²? - ProProfs

    What does E stand for in E=mc²?

    • Einstein's constant

    • Energy

    • Elasticity

    • Electric Impulse

    Correct Answer
    A. Energy
    Explanation
    The correct answer is Energy. In the equation E=mc², E represents energy. This equation, derived by Albert Einstein, relates energy (E) to mass (m) and the speed of light (c). It states that energy is equal to the mass of an object multiplied by the square of the speed of light. This equation is fundamental in understanding the relationship between mass and energy and is a cornerstone of Einstein's theory of relativity.

    Which of these does speed of light serve as that no any other constants serve as? - ProProfs

    Which of these does speed of light serve as that no any other constants serve as?

    • Limit of velocity

    • Distance of the Universe

    • Basic unit of distance

    • Central distance of the Earth

    Correct Answer
    A. Limit of velocity
    Explanation
    The speed of light serves as the limit of velocity because it is the maximum speed at which any information or matter can travel in the universe according to the theory of relativity. No other constant serves as this limit, making the speed of light unique in its role.

  • 4. 

    Which of these denotes the speed of light through a vacuum?

    • S

    • C

    • K

    • T

    Correct Answer
    A. C
    Explanation
    The symbol "c" is commonly used to represent the speed of light through a vacuum. This is based on the Latin word "celeritas," which means speed. In physics, "c" is a constant that represents the speed of light in a vacuum, which is approximately 299,792,458 meters per second.

    What is the exact value of the speed of light? - ProProfs

    What is the exact value of the speed of light?

    • 300,000 m/s

    • 186,000 m/s

    • 299,792,458 m/s

    • 3,000,000 m/s

    Correct Answer
    A. 299,792,458 m/s
    Explanation
    The correct answer is 299,792,458 m/s. This is the exact value of the speed of light in a vacuum. It is a fundamental constant in physics and represents the maximum speed at which information or energy can travel in the universe. It plays a crucial role in various scientific theories and has been measured and confirmed through numerous experiments and observations.

    What is the term given to the ratio between speed of light in a vacuum and the speed of light through any material? - ProProfs

    What is the term given to the ratio between speed of light in a vacuum and the speed of light through any material?

    • Light Ratio

    • Light Years

    • Refractive Index

    • Speed difference

    Correct Answer
    A. Refractive Index
    Explanation
    The term given to the ratio between the speed of light in a vacuum and the speed of light through any material is called the refractive index. Refractive index is a measure of how much light is bent or slowed down when it passes through a particular material. It is a fundamental concept in optics and is used to understand and predict the behavior of light as it travels through different media.

    How many miles does light travel per hour? - ProProfs

    How many miles does light travel per hour?

    • 689,000,000

    • 671,000,000

    • 780,000,000

    • 800,000,000

    Correct Answer
    A. 671,000,000
    Explanation
    Light travels at a speed of approximately 671,000,000 miles per hour. This is the correct answer because it is a widely accepted scientific fact that light travels at a constant speed in a vacuum, known as the speed of light. The speed of light is approximately 299,792,458 meters per second, which is equivalent to about 671 million miles per hour.

    C was derived as a constant from which of these Latin words? - ProProfs

    C was derived as a constant from which of these Latin words?

    • Cupio

    • Cutis

    • Coemo

    • Celeritas

    Correct Answer
    A. Celeritas
    Explanation
    The correct answer is Celeritas. Celeritas is a Latin word that means "swiftness" or "speed." It is the root word from which the English word "acceleration" is derived. The other options, Cupio, Cutis, and Coemo, do not have any connection to the concept of constant or speed.

    What does n represent in the formula, n = c / v? - ProProfs

    What does n represent in the formula, n = c / v?

    • Refractive Index

    • Light Years

    • Average speed of light

    • Distance travelled by light in vacuum

    Correct Answer
    A. Refractive Index
    Explanation
    The variable "n" represents the refractive index in the formula. The refractive index is a measure of how much a substance can bend light as it passes through it. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the substance. Therefore, "n" is the correct answer as it represents the refractive index in the given formula.

    Rate this question:

  • 10. 
    Which of these was an alternate symbol for the speed of light? - ProProfs

    Which of these was an alternate symbol for the speed of light?

    • V

    • S

    • U

    • μ

    Correct Answer
    A. V
    Explanation
    The symbol "V" was an alternate symbol for the speed of light.
