About This Quiz

Light is electromagnetic radiation within the spectrum of the electromagnetic rays that can be perceived by the human eye. The main source of light on Earth is the Sun. Sunlight provides the energy that plants use to create sugars mostly in the form of starch, which releases energy into the living things that digest them. This is a beginner's quiz about light. Answer these simple questions and learn interesting trivia.

    Which of the following is not a light source? Choose the correct answer - ProProfs

    Which of the following is not a light source? Choose the correct answer

    • Candle

    • Moon

    • Stars

    • Sun

    Correct Answer
    A. Moon
    Explanation
    The moon is not a light source because it does not emit light of its own. Instead, it reflects the light of the sun, making it appear bright in the night sky. The other options, candle, stars, and sun, are all sources of light.

    Light travels in straight lines.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Light travels in straight lines because it is a form of electromagnetic radiation that moves in a wave-like pattern. These waves propagate through space and other mediums by oscillating perpendicular to the direction of their motion. This oscillation causes the light to travel in a straight line unless it encounters an obstacle or is refracted or reflected by a surface. This property of light is fundamental and has been observed and studied extensively in the field of optics.

    We see light when it leaves our eyes.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    We do not see light when it leaves our eyes. In fact, we see light when it enters our eyes and is detected by the retina. The light enters the eye through the cornea, passes through the pupil, and then gets focused by the lens onto the retina. The retina contains cells called photoreceptors that convert the light into electrical signals, which are then sent to the brain for processing and interpretation, resulting in the sensation of vision.

    Why does the Sun look as if it is moving across the sky?

    • The sun is rotating

    • The Earth is spinning/rotating (on its axis).

    • The Earth is revolving around the sun

    • The earth is moving

    Correct Answer
    A. The Earth is spinning/rotating (on its axis).
    Explanation
    The Earth's rotation on its axis causes the Sun to appear as if it is moving across the sky. As the Earth spins, different parts of its surface are exposed to the Sun's light, creating the illusion of the Sun moving from east to west. This rotation gives rise to day and night, as well as the apparent movement of the Sun throughout the day.

    Sam does not know why Emily’s shadow moves. He asks his friends. Which friend has the correct answer? - ProProfs

    Sam does not know why Emily’s shadow moves. He asks his friends. Which friend has the correct answer?

    • Carlos

    • Nadia

    • Sam

    • Maya

    Correct Answer
    A. Maya
    Explanation
    Maya has the correct answer because she knows that Emily's shadow moves because of the rotation of the Earth. The movement of the Earth causes the position of the sun to change relative to Emily, resulting in the movement of her shadow. Maya's knowledge of this scientific phenomenon shows that she understands the reason behind the movement of Emily's shadow.

    The light intensity cannot be measured with sensors.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    This statement is false because light intensity can indeed be measured with sensors. There are various types of sensors, such as photodiodes or light-dependent resistors, that can detect and measure the intensity of light. These sensors convert the light energy into electrical signals, allowing for quantitative measurement of light intensity.

    Lucy and her teacher discuss shadows. Lucy thinks of four possible answers to the teacher’s question. Choose the correct answer. - ProProfs

    Lucy and her teacher discuss shadows. Lucy thinks of four possible answers to the teacher’s question. Choose the correct answer.

    • Wooden chair

    • Mosquito net

    • Glass window

    • Brick wall

    Correct Answer
    A. Mosquito net
    Explanation
    Lucy's teacher must have asked a question related to shadows and their characteristics. Out of the four options given, the correct answer is "Mosquito net" because it is a translucent material that allows some light to pass through, creating a diffused shadow. The other options, such as wooden chair, glass window, and brick wall, would create more defined and solid shadows due to their opaque nature.
