Mirror functions to show the image of whatever that you set in front of it. If you are standing in front the mirror and then raise your hand, you will see an image of a person raising his/her hand. However, the light will work differently when it hits a mirror. Actually, light is energy. Since energy cannot be created or destroyed, this light has to go somewhere when it hits the mirror surface.
Basically, the light bounces back at an angle rather than to pass through and it continues into the rest of the room. By using multiple mirrors, you will be able to reflect the light and also create interesting effect, especially when in a dark room with bright, colored lights. If you understand about the basic concepts, you will be able to use the mirrors and the light to create brighter, more open room. Just take a look at the following tips to know how to use mirrors to reflect light.
As the first step, you need to account for the angle of reflection. It is known that the light bounces back out with the same angle that it hits the mirror. You should know where the light will go can allow you to place the next mirror in such way which reflects the same beam.
The second step is to set up the mirrors. You need to place them facing each other and then close enough that the light does not fade between the each one. It is depending on the strength that you use. The stronger the light, the better you are searching for the dramatic effect.
The last step is to check the angles. You can start it by shining the single light at the first mirror. Try to watch how the light bounces off, and make sure that it hits across the mirror and slightly over from the first mirror.
