station broadcasts at a wavelength of 0.500 kilometers. Microwaves can have a wavelength of 12 cm. A fire place can give off photons with a wavelength of 1.5 x 10-3 millimeters and the X-rays used in a dentist’s office have a wavelength of 2.1 x 10-11 meters. Ultraviolet rays‚ the ones that give you sunburn or fade the colors of clothes have a wavelength of about 3.0 x 10-7 meters. From this data‚ what can you conclude about the energy of a photon with respect to its wavelength? Ans: Photons

absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1‚ in order to determine the maximum absorbance wavelength of KMnO4‚ we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm‚ and plotted the λ and A points; the λmax was 530nm. In part 2‚ the effect of concentration on the absorbance was examined. We prepared five differently concentrated (but

electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when the wavelength is larger‚ the energy that is being directed is spread out

like waves (Wave-Particle Duality‚ January 2010). There are times when light seems to act as both. At times‚ light appears to only travel in a straight line‚ as if it were made of particles. Yet other experiments show that light has a frequency or wavelength‚ just like a sound wave or water wave (Wave-Particle Duality‚ January 2010). “Until the 20th century‚ most physicists thought that light was either one or the other‚ and that the scientists on the other side of the argument were simply wrong.” (Wave-Particle

Effects of Changing Wavelength on Raphanus Sativus Abstract: Light from the Sun is a full spectrum of different wavelengths of light. Scientists refer to this light as “white light”. When the wavelength of visible light changes‚ so does the color seen by the eye. The shortest wavelengths visible to the human eye are violet (400 nanometers). The longest wavelengths visible the human eye are red (700 nanometers). Each plant is affected differently by the changing wavelengths of light. The purpose

source. Prequency and Wave Length In physics‚ the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave’s shape repeats.[1] It is usually determined by considering the distance between consecutive corresponding points of the same phase‚ such as crests‚ troughs‚ or zero crossings‚ and is a characteristic of both traveling waves and standing waves‚ as well as other spatial wave patterns.[2][3] Wavelength is commonly designated by the Greek letterlambda (λ)

Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables
