1) What are called luminous objects?Ans. |
|
Answer» A luminous object is one that gives off light. In other words, it glows (or shines) of its own accord. To be able to glow, the object must have its own source of energy. Some examples of luminous objects are a burning candle, a light bulb, the sun and other stars, fluorescent materials and tube lights, among other things. Fluorescent materials store energy given by other luminous objects and release light in wavelengths that cannot be seen in visible light. |
