The term for the point where reflected light rays meet along an optical axis is the focal point. This is where parallel light rays converge or diverge after being reflected or refracted by a lens or mirror.
The term that indicates the point where reflected light rays meet along an optical axis is the focal point.
An optical density of 1 indicates that 90% of light is absorbed by the material being measured. It is commonly used in spectrophotometry to quantify the amount of light absorbed by a sample. A higher optical density value indicates greater light absorption.
The focus of a concave mirror is the point on its optical axis where light rays parallel to the axis converge after being reflected.
Optical density is a measurement of how much light is absorbed or transmitted by a material. It is often used to quantify the amount of a substance in a solution by measuring the absorbance of light passing through it. A higher optical density indicates more absorption of light.
In plasma, optical thickness refers to the measure of how effectively the plasma interacts with electromagnetic radiation, such as light. It accounts for the absorption and scattering of light as it passes through the plasma. A higher optical thickness indicates a greater interaction between the plasma and light.

optical fibres are made out of materials with high refractive index, this ensures that the light is always reflected back inside the fibre..
Optical microphones are type of a microphone in which the movement of the microphone membrane is sensed optically. Usually there is a light source and photo-detectors to capture the light reflected back from the membrane.

Some of the light injected by the optical transmitter is lost along the length of the fiber as the light travels. The optical receiver needs a minimum amount of light to function properly. Therefore optical repeaters must be installed at intervals along the path to keep the light level above the level needed by the last receiver.
Optical power refers to the ability of a lens or optical system to converge or diverge light. It is typically measured in diopters (D) and indicates the strength of the lens in focusing light onto the retina. Positive optical power converges light (useful for correcting hyperopia), while negative optical power diverges light (useful for correcting myopia).

It accounts for the absorption and scattering of light as it passes through the plasma. A higher optical thickness indicates a greater interaction between the plasma and light.
This is known as an episcope.
It is used to observe features of stars, planets, and other celestial objects by their visible light (generated or reflected).
