Wavelength

drawn: Figure 2- A graph showing the relation between concentration of bromophenol blue in M and their absorbance for the acidic form of the molecule, showing the molar absorptivity constant of the molecule at wavelengths 440 nm and 590 nm. The reading with concentration 6 x 10-4 M at wavelength 440 nm was discarded as it is too off from the trend line that it is not following the trend at all. The deviated reading may be caused by the cross contamination when using the same cuvette to…

I would like to gain knowledge regarding galaxies, black holes, and exoplanets. A galaxy is a system that contains millions of stars, gas and dust held together by gravitational attraction. A black hole is a place in space where the gravitational force is immense, making the escape of matter and radiation impossible. An exoplanet is a planet that orbits a star, other than the sun, beyond our solar system. By choosing these targets, I wish to learn about how the first galaxies were formed, why…

optimal wavelength of maximum cranberry juice absorption was determined to be 525 nm. The calibration curve could then be created by measuring the absorbance of known concentrations, 5% to 25%, of cranberry juice at 525 nm, and generating a calibration curve of absorbance vs concentration. The absorbance of the cranberry apple juice was then measured at the wavelength of maximum absorbance. Absorbance is a measure of the amount of light that passes through a sample at a selected wavelength.…

physicist Louis de Broglie made an assertion. His Consideration of Einstein's equation of wavelength lambda to momentum p, de Broglie said that the relationship determines the wavelength, in the relationship: λ = h / p Where h is the Planck's constant This wavelength λ is called the de Broglie wavelength. The de Broglie hypothesis states that particles of matter also have wavelengths and can behave as waves, like photons .According to String ,both types of particles…

thinking that photosynthesis would react better with red light wavelengths. Although, our thinking was not completely accurate. When comparing red light to white light, the rate of photosynthesis did have a significant change. However, white light was still more effective than either of the light treatments. This is because white light is composed of all colors, giving the photosynthesis to opportunity to absorb more from its specific wavelength that provides for the best rate of photosynthesis.…

infrared light Microwaves- wavelength which is longer than that of infrared light and therefore has less energy Efficiently absorbed by water → can heat substances which contain water Used for radars and microwave ovens Radio Waves- The longest type of wavelength Used to transmit the signals responsible for AM and FM radio Cell phone, television, etc. Interference- when wavelengths cancel each other out or build each other up Constructive Interference- when two wavelengths of equal amplitude…

example, if a solution was viewed as the color red, then red light was transmitted by the solution while the complementary color, green, was absorbed. Beer’s Law stated that the amount of light that passed through a sample was limited by the light’s wavelength, the distance travelled by the light, and the concentration of the substance…

based on the accurate determination of the wavelength in the medium. The principle of ultrasonic interferometer for the measurement of velocity is determination of the accurate wavelength in the medium. Ultrasonic waves of known frequency are produced by quartz crystal fixed at the bottom of the cell. The quartz crystal fixed at the bottom of cell produced ultrasonic waves of known frequency. These waves are reflected…

reactions powered by sunlight. The photosynthetic pigments present in a plant, such as chlorophyll, allow the plant to harness energy from the sun and perform the reactions necessary for photosynthesis. Various wavelengths of light from the sun are used to power photosynthesis, and different wavelengths correspond to different colors. Plants tend to absorb very little green light, reflecting most of it and causing plants to appear green to the human eye. On the other hand, previous research…

absorbance/concentration, the higher the SPF value and the lower the absorbance the lower the SPF. Also Figure 8 has the same pattern, but the absorbance values correspond to a different wavelength. However, one very noticeable difference in the absorbance/concentration vs SPF and the absorbance vs SPF graph at a wavelength of 312 nm was the position of the SPF 15 sunblock. Sunblock is different from a sunscreen because a sun blocker, blocks the light from reaching the skins surface, thus…
