Luminous objects usually give out the light that they make on their own. An example of a luminous object is a star or an LED lamp.
Transparent objects are the sorts of objects that light passes through. Translucent objects allow the partial transmission of light. Opaque objects prevent the transmission of light.
The sun produce light and nuclear energy
Light has the property of being an electromagnetic wave.
Anything that reflects, absorbs, or scatters light can form some kind of shadow.

Objects that have large amplitudes typically produce louder and more intense sounds compared to objects with smaller amplitudes. The sound may also be perceived as more powerful and often can be heard over longer distances.
light and thermal energy
Large objects that vibrate slowly produce lower frequency notes, which are perceived as lower in pitch. This is because the frequency of a sound wave is directly related to the speed of the vibrations creating it.
