    • D.

      1, 2 dan 3

    Correct Answer
    C. 1 dan 3
    Explanation
    The correct answer is 1 and 3. This is because both a solar eclipse and a rainbow are phenomena that occur due to the propagation of light. During a solar eclipse, the moon blocks the light from the sun, causing a temporary darkness during the day. This demonstrates how light travels in a straight line. Similarly, a rainbow is formed when sunlight is refracted, or bent, by water droplets in the air, creating a spectrum of colors. Again, this shows how light travels in a straight line and interacts with its surroundings. Therefore, both events are examples of light propagation.

    • C.

      Perambatan

    • D.

      Perenggangan

    Correct Answer
    B. Pembiasan
    Explanation
    The correct answer is "pembiasan". When a pencil is placed in a glass of water, it appears to be broken or bent because light rays passing from the water to the air undergo refraction. Refraction is the bending of light as it passes from one medium to another with a different optical density. This causes the light rays to change direction and makes the pencil appear to be distorted.

    Rate this question:

  • 18. 

    Cahaya yang datang dari zat yang lebih rapat menuju zat yang kurang rapat akan dibiaskan ....

    • A.

      Sejajar dengan garis normal

    • B.

      Tegak lurus dengan garis normal

    • C.

      Menjauhi garis normal

    • D.

      Mendekati gars normal

    Correct Answer
    C. Menjauhi garis normal
    Explanation
    When light travels from a denser medium to a less dense medium, it undergoes refraction. Refraction is the bending of light as it passes from one medium to another. The amount of bending depends on the refractive indices of the two media. In this case, since the light is going from a denser medium to a less dense medium, it will be bent away from the normal line. So, the correct answer is "menjauhi garis normal" which means "away from the normal line" in English.

    • C.

      Fatamorgana

    • D.

      Siang dan malam

    Correct Answer
    B. Pelangi
    Explanation
    A rainbow is formed when sunlight is refracted, or bent, as it passes through water droplets in the air. This refraction causes the different colors of light to separate and form a circular arc in the sky. Therefore, a rainbow can be considered as a phenomenon of light decomposition.
