What does it mean to transmit light?

Answer 1

Atoms, molecules, or solids that are excited to high energy levels can decay to lower levels by emitting radiation (emission or luminescence). For atoms excited by a high-temperature energy source this light emission is commonly called atomic or optical emission (see atomic-emission spectroscopy) and for atoms excited with light it is called atomic fluorescence (see atomic-fluorescence spectroscopy). For molecules it is called fluorescence if the transition is between states of the same spin and phosphorescence if the transition occurs between states of different spin. Separate documents describe molecular fluorescence, which can be done with compact instruments, and laser-induced fluorescence.

The emission intensity of an emitting substance is linearly proportional to analyte concentration at low concentrations. Atomic emission and molecular fluorescence are therefore useful for quantitating emitting species.

Answer 2

Light is also a kind of energy. It is transformed not as mechanical wave. Because mechanical wave definitely needs a material medium to get propagated. Sound energy is transmitted only as a mechanical wave. Without air medium sound cannot be propagated. But light does not need such material medium. It can pass even through free space in the form of electromagnetic wave.

The general concept is: When any disturbance is made any where at any time in the space that would be propagated to other places. This is what we call transmission of light disturbance.

Answer 3

it means to take the light and move it like a reflection

Answer 4

Light. Particles and waves makeup light. Quantum mechanics.
