Questions and Answers
  • 1. 

    Out of these four options, which surface can light pass through?

    • A.

      Opaque

    • B.

      Transparent

    Correct Answer
    B. Transparent
    Explanation
    Light can pass through a surface that is transparent. Transparency refers to the property of allowing light to pass through without scattering or diffusing it. Transparent materials such as glass, water, and air allow light to pass through them, making objects on the other side visible. In contrast, opaque surfaces do not allow light to pass through, blocking the transmission of light and making objects behind them invisible.

    _______  is not a source of light because the suns light reflects onto it.

    Correct Answer
    moon
    Explanation
    The moon is not a source of light because it does not produce its own light. Instead, it reflects the light from the sun. This is why we see the moon shining in the night sky. If the moon were a source of light itself, it would emit its own light and not rely on the sun's light for illumination.

    Objects that have that have lights of their own are called____________ of light.

    Correct Answer
    sources
    Explanation
    Objects that have their own lights are called sources of light. These objects emit light energy, making them the origin or starting point of light rays. They can include natural sources like the sun, stars, and fire, as well as artificial sources like light bulbs and lamps. These sources emit light in various forms, such as visible light, infrared light, or ultraviolet light.

  • 4. 

    Out of these four questions, which one is not a source of light?

    • A.

      Sun

    • B.

      Moon

    Correct Answer
    B. Moon
    Explanation
    The moon is not a source of light because it does not produce its own light. Instead, it reflects the light from the sun. The sun, on the other hand, is a source of light as it emits its own light and heat. Therefore, the moon is the correct answer as it does not emit light independently.

    Rate this question:

  • 5. 

    When an object is blocking the path of light, it creates a _______.

    Correct Answer
    shadow
    Explanation
    When an object blocks the path of light, it creates a shadow. Shadows are formed when light is obstructed by an opaque object, preventing it from reaching a surface. The object casts a silhouette on the surface behind it, creating a darker area where light is not able to reach. Shadows are formed due to the absence of light in the blocked area, resulting in a contrast between the illuminated and shaded regions.

    Rate this question:

  • 6. 

    How is a shadow formed?

    • A.

      When an object is blocking the lights path.

    • B.

      When the light turns to the east.

    • C.

      When the light turns to thw west

    Correct Answer
    A. When an object is blocking the lights path.
    Explanation
    A shadow is formed when an object blocks the path of light. When light rays from a source hit an object, they are unable to pass through it, resulting in the formation of a shadow on the opposite side of the object. The shadow is created because the light rays cannot reach the surface behind the object, causing that area to be darker compared to the surrounding areas.

Although there were earlier versions of electric lamps, Edison's design was the first to use a carbon filament that could last for a significant amount of time. His invention revolutionized the way we illuminate our homes and buildings, leading to widespread adoption of electric lighting and transforming the world.
