Production of Light Questions and Answers

  • 1. 

    A _______is a light producing electronic device that allows an electric current to flow in only one direction.  Now used in Christmas lights illuminated signs, and traffic lights.

    Explanation
    An LED (light-emitting diode) is a light producing electronic device that allows an electric current to flow in only one direction. LEDs are commonly used in various applications such as Christmas lights, illuminated signs, and traffic lights.

    A _____________ light tube is filled with very low-pressure mercury vapour. The inner surface of the tube is also coated with a fluorescent material. 

    Explanation
    A fluorescent light tube is filled with very low-pressure mercury vapor. The inner surface of the tube is also coated with a fluorescent material.

  • 3. 

    Light from an electric discharge, such as lightning is produced by an electric current passing through a _______. 

    Explanation
    Light from an electric discharge, such as lightning, is produced by an electric current passing through a gas. When an electric current passes through a gas, the gas molecules become excited and release energy in the form of light. This phenomenon is known as gas discharge, and it is the reason why we see light from sources like lightning.

    Fluorescence occurs when an object absorbs _______________ light and immediately releases the energy as visible light.

    Explanation
    Fluorescence occurs when an object absorbs ultraviolet light and immediately releases the energy as visible light. Ultraviolet light has a higher energy level than visible light, so when an object absorbs it, the electrons in the object's atoms become excited. As the electrons return to their original energy level, they release the excess energy in the form of visible light, resulting in fluorescence.

    Rate this question:

  • 5. 

    ______________________ is the production of light as a direct by-product of a chemical reaction. Light sticks operate by causing two chemicals to mix.

    Explanation
    Chemiluminescence is the production of light as a direct by-product of a chemical reaction. In the case of light sticks, chemiluminescence occurs when two chemicals are mixed together. This reaction releases energy in the form of light, resulting in the glow observed in light sticks. Therefore, chemiluminescence is the correct answer as it accurately describes the process of producing light through a chemical reaction.

    Rate this question:

  • 6. 

    When chemiluminescence occurs in living organisms, scientists call it ____________________.

    Explanation
    When chemiluminescence occurs in living organisms, scientists refer to it as bioluminescence. This phenomenon involves the emission of light by living organisms as a result of a chemical reaction. Bioluminescence is commonly observed in various marine organisms such as jellyfish, plankton, and deep-sea fish. It is a fascinating natural process that has evolved in certain organisms to serve various purposes such as attracting mates, luring prey, or warning predators. The light emitted during bioluminescence is produced by the interaction of a luciferin molecule with an enzyme called luciferase, which generates light without producing heat.

  • 7. 

    Any object, as it gets hotter and hotter, will eventually produce __________ of varying colors.

    Explanation
    As an object gets hotter and hotter, it will eventually start to emit light. This light can have varying colors depending on the temperature of the object. This phenomenon is known as incandescence, where the object's atoms become excited and release energy in the form of light. The color of the light emitted is determined by the temperature, with cooler objects emitting red or orange light, and hotter objects emitting blue or white light.

    Rate this question:

  • 8. 

    The process of producing light as a result of high temperature is called _______________.

    Explanation
    Incandescence refers to the process of producing light as a result of high temperature. When an object is heated to a high temperature, it begins to emit visible light, creating a glowing effect. This phenomenon is commonly observed in incandescent light bulbs, where a filament is heated to produce light. Incandescence is a form of thermal radiation and is characterized by the emission of a continuous spectrum of light.

    Rate this question:

  • 9. 

    Fluorescence is a phenomenon where a material emits light immediately upon absorption of energy from an external source.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Fluorescence is a phenomenon where a material absorbs energy from an external source, such as light or heat, and then emits light almost immediately after the excitation ceases. This emitted light typically has a longer wavelength than the absorbed radiation, resulting in a characteristic color change. Common examples of fluorescence include fluorescent lamps, certain minerals, and fluorescent dyes used in various applications.

    Rate this question:

  • 10. 

    Phosphorescence is a type of luminescence where a material continues to emit light for some time after the excitation source has been removed.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Phosphorescence is indeed a type of luminescence characterized by the emission of light after the material has been exposed to an excitation source and then the source is removed. Unlike fluorescence, which emits light almost immediately after excitation, phosphorescence involves a delayed emission of light due to the relaxation of electrons to their ground state occurring over a longer period of time. This phenomenon can be observed in certain materials like glow-in-the-dark toys, certain minerals, and phosphorescent paints.
