Reflection
When the light combine with the speed in a photoelectric effect it produces a picture of the object.
Depends on the surface of the object that the light is projected on. If the object has a polished surface like an inoxidable steel, or the object is a mirror, the light will produce a reflexion or the light comes back when it hits the mirror. Behind any object, is formed a shadow, since such object is not a glass.
This device is commonly known as a film camera.
Light bulbs. The filament in the bulb is heated in order for it to glow and produce light. This can be considered as a conversion of energy where heat energy is being transferred in light energy.
This is known as an episcope.
The name of the device that produces coherent light is LASER.
A luminous object can reflect light off other light sources. But it can also produce its own light.
A laser is a device to produce an intense monochromatic beam of coherent light.
That device is a telescope.
No. Any object that is hot enough will produce light, regardless of what heated it.
Heat can not produce light without heating a certain object or material meaning heat by itself cannot produce light on its own.
A laser.
We call it 'wingardiem leviosa'
Reflection
A luminous object is an object that can reflect light! examples of these objects are the moon, etc. hope that helped :)
