Study Notes
Light and Shadows
- Luminous objects emit their own light.
- The region without light that forms behind an object kept in the path of light is called a shadow.
- Opaque objects cast dark shadows.
- Opaque objects do not allow light to pass through them.
- Light can be classified into three types based on emission: luminous, illuminated, and reflected.
Eclipses
- A solar eclipse occurs when the moon comes between the sun and the earth.
- The definition of a solar eclipse is when the moon's shadow falls on a specific region of the earth, blocking the sun's light.
Objects and Light
- Translucent objects allow light to pass through them, but scatter it in different directions, making it difficult to see objects clearly.
- Examples of translucent objects include frosted glass, wax paper, and tissues.
- Transparent objects allow light to pass through them, enabling objects to be seen clearly.
- The difference between umbra and penumbra shadows is that umbra is the darker inner shadow where the light is completely blocked, while penumbra is the lighter outer shadow where the light is only partially blocked.
