Briefly describe the characteristics of the electromagnetic spectrum and relate wavelength to the quantity of energy obtainable. Which type of energy photon can damage DNA directly? Describe the characteristics of the electromagnetic spectrum and relate wavelength to the amount of vitality out there. Explain how the wavelengths absorbed and mirrored decide the colour of a pigment. A radio station has a frequency of 96.5 MHz.

These observations allow astronomers to determine sure bodily characteristics of objects, similar to their temperature, composition and velocity. If every thing above 50% of light vitality mirrored is seen to the human eye, is purple light a part of the combination of colours seen in mild mirrored by chlorophyll? Find the frequency range of visible mild, provided that it encompasses wavelengths from 380 to 760 nm. If red mild of wavelength 700 nm in air enters glass with index of refraction 1.5, what is the wavelength of the light in the glass? Express your answer in nanometers to three important figures. The colours of the spectrum of white mild are violet, indigo, blue, green, yellow, orange, and red .

So to do that, we need to think about a few equations that we all know. The first one talks about power and vitality is equal to Planck’s constant sorts frequency. So by seeing this equation since Plank’s fixed as a constant, we see that frequency and vitality are immediately proportional. So as one goes up, the other goes up, the higher the frequency, the higher the power.

It is also one of many highest frequencies within the spectrum and is the bottom frequency within the visible spectrum. Weak violet light will eject just a few electrons, however their most kinetic energies are higher than those for intense light of longer wavelengths. The content that follows is the substance of General Chemistry Lecture 24. In this lecture we Introduce the ideas of electromagnetic radiation, wavelength, frequency and the Photoelectric Effect. Different kinds of lights have an result on the best way our eyes view colours.

If you’re looking at a Yellow flower, what wavelength of light are reflected by the pigments in the flower? Which of the following colours of light can be absorbed LEAST by a blue pigment? A) blue b) green c) yellow d) purple e) they would all be absorbed equally.

On the other side, next to the seen mild spectrum is the infrared radiation… In a spectroscopy experiment, electromagnetic radiation of a specified range of wavelengths is allowed to move through a sample containing a compound of interest. The sample molecules take up power from some of the wavelengths, and in consequence jump from a low power ‘ground state’ to some greater power ‘excited state’. Other wavelengths aren’t absorbed by the sample molecule, in order that they pass on by way of.

Since wavelength is inversely proportional to the frequency, we are ready to perceive that the longer the wavelength of the light, the decrease is the frequency. In the identical manner, the shorter the wavelength, the upper will be the frequency of the sunshine. The violet colour is claimed to have the shortest type of wavelength whereas the pink color is said to have the longest wavelength. Red waves have a relatively long wavelength , and violet waves are much shorter – roughly half that. Violet waves have the most energy of the seen spectrum. The setup depicted in Figure 4.6 is used in a diffraction experiment using X-rays of zero.26 nm wavelength.
