Cuvettes have different surfaces to accommodate various types of optical measurements. Smooth, clear surfaces are used for standard transmission measurements, while frosted or frosted-sidewall surfaces help reduce glare and reflections for fluorescence or absorbance measurements. Some cuvettes also have special optical coatings to enhance sensitivity or reduce background interference.
Objects move on different surfaces by friction.
Balls bounce differently on different surfaces due to differences in elasticity, surface texture, and friction. Softer surfaces absorb more of the ball's energy, resulting in a lower bounce. Smoother surfaces allow for a more predictable bounce, while rough surfaces can cause the ball to bounce in unpredictable directions.
No, the friction between two surfaces depends on factors such as the roughness of the surfaces, the force pressing them together, and the materials involved. Different surfaces will have different coefficients of friction which determine how much force is required to overcome the friction between them.
Yes, the frictional force between two surfaces depends on the type of surfaces in contact. The roughness and material of the surfaces impact the coefficient of friction, which determines the magnitude of the frictional force. Smooth surfaces generally have less friction than rough surfaces.
Why do they have different surface temperature
It is your control. Your baseline reading.

Glass will absorb radiation below 320nm whereas quartz will allow transmission of the UV wavelengths. So use glass cuvettes for wavelengths in the visible range from 380nm to 780nm and quartz cuvettes for wavelengths below 380nm.

The surfaces are the same length and have different material.
Box graters have four different cutting surfaces. Three grating surfaces and one slicing surface are standard.

Reference cuvettes are used in spectrophotometry to calibrate the instrument and ensure accurate measurements. By measuring the absorbance of a known standard in the reference cuvette, any variations or deviations in the spectrometer's readings can be identified and corrected for, leading to more precise and reliable results.

No. Surfaces are different
A cuvette is a very small tube that is sealed at one end and made of plastic, glass, or fused quartz. The reason why the cuvettes that are used in the 200-400 nm range are made of silica is because of the shifts in the chemical equilibria.
