what is the difference in the percent transmittance between the unboiled?

The cuvette with the unboiled chloroplasts that had been exposed to light showed the biggest change in percent transmittance (2.6%), which indicates that the amount of light available has a very big effect on the rate at which the light reactions of photosynthesis occur.

Ultraviolet Protection Factor (UPF) indicates how much UV radiation (both UVB and UVA) a fabric allows to reach your skin. For example, a UPF 50 fabric blocks 98 percent of the sun's rays and allows two percent (1/50th) to penetrate, thus reducing your exposure risk significantly.

['First make sure the both weights have the same units.', 'Take your experimental yield and divide it by the theoretical yield.', 'Multiply this value by 100 to find the percent yield.']

Absorbance values greater than or equal to 1.0 are too high. If you are getting absorbance values of 1.0 or above, your solution is too concentrated. ... At an absorbance of 2 you are at 1%T, which means that 99% of available light is being blocked (absorbed) by the sample.

Uncoated is bare wire, coated is tinned wire. The diameter of the conductor is the same after tinning so the diameter of the copper is reduced about . 002" to make up for the addition of the tinning. This increases the resistance of the conductor.

The refractive index depends not only on the wavelength used to measure, but also on the temperature of the solution being measured. There is a direct relationship between the refractive index and BRIX. The measured refractive index is converted directly into weight percent sucrose content (°Brix).

Focal length is increases with increase in wavelength of light passed. Focal length is directly proportional to wavelength of light passed. As red light has higher wavelength, it refracts less and has greater focal lens. On the contrary, blue light converges more and has small focal length.

The basic difference between the two is that the grating spectrum is due to diffraction and dispersion spectrum is due to dispersion. We can hardly get higher order spectrum peaks in dispersion spectrum(only of order 1) but in grating spectrum we get higher order peaks(we can see of order 2 too).

Unaveraged: Displays unaveraged results. Averaged: Displays averaged results. Nodal Difference: Computes the maximum difference between the unaveraged computed result (for example, total heat flux, equivalent stress) for all elements that share a particular node.

UV light that has wavelengths longer than 200 nm passes through liquid water, while shorter wavelengths are strongly absorbed by liquid water. ... Note that both UVA (320-400 nm) and UVB (290 to 320 nm) are above the 200 nm drop, and are not highly absorbed by water.

While light filtering treatments avoid up to 95 percent of the glow from street lamps and sunlight, the room darkening type cuts out approximately 95-99 percent of brightness. In contrast, the blackout style uses a special material designed to eliminate illumination by 100 percent.

The difference between WDM and dense wavelength division multiplexing (DWDM) is one of degree only. DWDM spaces the wavelengths more closely than WDM, and therefore DWDM has a greater overall capacity.

What is the difference between frosted and obscure glass? ... However, this is not the same as being opaque – obscure glass still allows large amounts of light to pass through it, illuminating an area, while an opaque surface, such as a wall, doesn't allow any light through.

The simple answer is that it depends on the medium it travels through. specifically it is determined by the permittivity (epsilon) and magnetic permeability (mu) at the wavelength of the photon.

Traditional black lights emit an average wavelength of 365 nm and have a filter (often ordinary glass) to eliminate anything below 320 nm. Ordinary glass filters medium and short wave ultraviolet light, while passing visible and long wave ultraviolet light.

The absorbance is directly proportional to the concentration (c) of the solution of the sample used in the experiment. The absorbance is directly proportional to the length of the light path (l), which is equal to the width of the cuvette.

The difference between guided and unguided transmission is the type of path used. Guided transmissions generally mean that the medium is using copper wires or optical fibers whereas unguided transmissions general use wireless mediums.
