What are the uses of CCD? CCDs are used in optical microscopes because they can possess over 10 million pixels, which enables many samples to be seen clearly, as well as a low noise ratio, ability to image in color, high sensitivity and a high spatial resolution which all contribute to the high-quality images that […]
What factors affect color?
What factors affect color? Factors Affecting How We See Color Lighting: Light plays a HUGE role in color perception. Age: As we get older, our perception of color starts to fade. Poor Color Memory: Human color memory is horrible! Retinal Fatigue: Our eyes get tired very easily. What Colour paint makes a room look bigger? […]
How do you find the wavelength of a yellow light?
How do you find the wavelength of a yellow light? The frequency (f) and wavelength (d) are related by the equation f = c/d, where c is the speed of light (approximately 2.99 x 10^8 meters per second). A specific yellow light might be 570 nanometers in wavelength, therefore, (2.99 x 10^8)/(570 x 10^-9) = […]

How accurate is a spectrophotometer?
How accurate is a spectrophotometer? The minimum is not sharp and good results can be expected in a transmittance range from 0.2 to 0.6 or an absorbance range from 0.7 to 0.2. An inspection of the graph below indicates that transmittance values of 0.1 and 0.8 are the outside limits between which one can expect […]
Is a Van de Graaff generator dangerous?
Is a Van de Graaff generator dangerous? Preliminary cautions: The Van de Graaff can produce a spark that is simply irritating or quite dangerous. A spark several centimeters long can be the equivalent of 100 000 volts or more. What is the principle of the Van de Graaff generator? The Van De Graaff generator works […]
What are the noise control methods?
What are the noise control methods? Extraction, ventilation, cooling, openings in walls and enclosures. Instead of fitting silencers, it is often possible to achieve a 10 – 20 dB reduction in airborne noise from a duct or opening by lining the last bend in the ductwork with acoustic absorbent (foam or rockwool / fibreglass). Which […]
