Superachromatic Waveplate

No, a half-silvered mirror can only reflect about half of the light that strikes it. The rest is transmitted through the mirror. To create a perfect reflection, a fully reflective mirror is needed.

A half-silvered mirror works by using a thin layer of metal, typically silver, that is only partially reflective. This allows for some light to pass through while the rest is reflected. The angle of the mirror determines how much light is transmitted or reflected.

A half-silvered mirror, also known as a semi-silvered mirror, is a type of mirror that reflects about half of the light that strikes it and transmits the other half. This allows for the splitting and manipulation of light beams.

Achromatic waveplate is made of two or more matched birefringent crystals, where the retardation changes are minimized as the wavelength changes. These achromatic waveplates are used for tunable lasers, multiple laser-lines and other broad spectrum sources. Super-achromatic waveplate consists of three achromatic waveplates based on Pancharatnama's design is used for modulator in polarimeter.

A photon is a fundamental particle of light that carries electromagnetic energy. It has no mass and travels at the speed of light.

Half-silvered mirrors are often used in optical experiments and devices, such as interferometers, to manipulate and control light beams. They can also be used to create optical illusions and in optical computing.
