Optics - Light Quiz - Quiz


Questions and Answers
  • 1. 

    The sun provides energy in the form of light through a process called ________  _______.  It occurs when two atoms that naturally repelled each other are pulled together by  a superior force and the atoms fuse together

    The correct answer is "nuclear fusion". Nuclear fusion is a process in which two atoms are brought together by a superior force, causing them to fuse and release energy in the form of light.

    Nothing moves faster than the speed of ____________.

    Light is the fastest thing in the universe. According to the theory of relativity, the speed of light in a vacuum is constant and is approximately 299,792,458 meters per second. No other object or particle can travel faster than this speed. Therefore, nothing moves faster than the speed of light.

    A _________________ object is one that produces light.

    A luminous object is one that produces light. It emits its own light and is capable of illuminating its surroundings. This can include natural sources of light such as the sun or fire, as well as artificial sources like light bulbs or LED lights. Luminous objects are distinguished from non-luminous objects, which do not produce their own light and can only be seen when illuminated by a luminous source.

    •Unlike heat and sound energy which requires a _________________  (a physical substance) to move, light does not.

    Light is a form of energy that can travel through empty space or a vacuum. Unlike heat and sound energy, which require a medium (a physical substance) to transfer or propagate, light does not need a medium to move. This is because light is made up of electromagnetic waves, which can travel through space without the need for particles or molecules to carry them. Therefore, light can travel through a vacuum, such as outer space, as well as through transparent substances like air, water, or glass.

    •Light is classified as an ___________________    ____________________.

    Light is classified as an electromagnetic wave because it consists of oscillating electric and magnetic fields that propagate through space. Electromagnetic waves can travel through a vacuum and do not require a medium for transmission. Light, along with other forms of electromagnetic radiation such as radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays, all exhibit wave-like properties such as wavelength, frequency, and amplitude.

    White light is not a single colour; it is made up of a mixture of the _________ colours of the rainbow.

    White light is not a single color; it is made up of a mixture of the seven colors of the rainbow.
