Vocabulary Questions: 1. Explain what gamma ray bursts are, using information from the article. Gamma ray bursts are the brief flickering of gamma ray light occurring from distant galaxies, but particularly occurring from a star exploding along with forming a black hole. When it comes to gamma rays, it’s the shortest wavelength in the electromagnetic spectrum. Making it deadly to humans. 2. How do frequency and wavelength relate to each other? Use details and examples from the text in your answer. Frequency and wavelength are related to one another because frequency describes the number of waves that of which passes by a point during one second. Wavelength is related on accounts to the distance from a peak of one wave to the peak of
Absorbance was defined as: log I_o/I where I_o is incident light and I is the transmitted light. Fluorescence emission spectrum is different from fluorescence excitation spectrum because it records different wavelengths of chemical s...
Your answer should be of sufficient length to adequately address these criteria, meaning that your answer should be a brief paragraph for each item.
The Effect of Wavelength on Photosynthesis Rate Aim: To be able to To investigate how different wavelengths (colors) of light affect the photosynthetic rate of the synthetic. I will use a pant that is a pond weed called elodea. I will measure the rate of photosynthesis by measuring the amount of o2 given off in bubbles per minute from the elodea. I will do this by placing the Elodea in a test tube with sodium hydrogen. carbonate then I will vary the light wavelength (color) using colored.
Imagine a massive celestial object in space, so densely packed with matter that nothing can ever escape it, not even light- that’s what black holes are. They are formed by large stars- stars that are way larger in size (20 times or more) than the sun. When such massive stars run out of fuel in its course, it can no longer sustain its heavy weight. They rapidly collapse causing colossal of explosions called supernova.
7. Explain what situations are considered "severe or pervasive" and why these terms are important.
Light is both part particle and part wave. Light is “the electromagnetic radiation that may be perceived by the human eye”. It consists of photons, which are massless bundles of concentrated electromagnetic energy. Light’s lower frequency is red, and the higher frequency is blue. Like sound, light has frequencies humans can’t detect. Ultraviolet light is at a frequency higher than violet, and infrared is at the frequency lower than the red of visible light. We get UV (ultraviolet) rays from the sun, and infrared is used in night vision to see better.
Supernovas are extremely powerful explosions of radiation. A supernova can give off as much energy as a Sun can within its whole life. A star will release most of its material when it undergoes this type of explosion. The explosion of a supernova can also help in creating new stars.
Gamma radiation/emission – Gamma ray emission can be found when either alpha or beta decay occurs. Gamma rays are high energy electromagnetic rays. Gamma radiation is just the excess energy of the reaction being shed off, gamma rays do not effect mass numbers or atomic numbers. 6027Co 6028Ni + 0-1e + y
A spectrum is an image or distribution of colour of any electromagnetic radiation arranged in a progressive series according to wavelength.
Radiation is a frightening concept. It has lead to many an untimely death in the past 70 years, ranging from victims of atomic bombs in Japan to physiologists experimenting without taking proper safety precautions. The most dangerous form of radiation can be devastating to the body, weakening or eliminating the immune system and tearing the very DNA in one’s cells apart. This form is referred to as ionizing radiation, and even the least harmful potencies - such as x-rays and UV light - can increase the risk of cancer and other health problems. It has enough energy to knock electrons out of atoms in a process called ionization.
The proportionality constant which relates frequency to field intensity is a well-known atomic constant the gy...
First of all what is a Gamma Ray? A gamma ray is a high energy ionized radiation (EPA). Gamma photons have about 10,000 times more energy as photons (EPA). Along with that gamma rays wavelengths are so short they have to be measured in nanometers (EPA). They also are the strongest type of radiation which makes them the most dangerous. How are Gamma rays dangerous? A gamma-ray photon has enough energy to damage atoms in your body and make them radioactive (Christian, Eric). Gamma ray radiation also causes murderous burn, breast and a lung and thyroid cancer, genetics illnesses (Asiye, Gul). But when did we even discover gamma rays? In 1896 Henri Becquerel, a French Physicist, discovered gamma rays, he called it metallic phosphorescence (EPA). Becquerel had found gamma radiation being emitted by radium (EPA).
waves are further divided into two groups or bands such as very low frequency (
Planck's constant x speed / wavelength Different colours of light have the same speed, but different wavelengths, which, in the above equation, changes the value for energy, which is the solar cell output. And, because the wavelength is the denominator for this equation, we can make the statement, that 'the larger the wavelength, the lower the energy'. A colour of light with a larger wavelength will result in a lower solar cell energy output. The two factors that I am going to study in this experiment are: 1. Changing power at the light source 2.
