Ultraviolet
|
IMDB rating: 3.90 Plot: Set in the late 21st century, a subculture of humans have emerged who have been modified genetically by a vampire-like disease, giving them enhanced speed, incredible stamina and acute intelligence, and as they are set apart from “normal” and “healthy” humans, the world is pushed to the brink of worldwide civil war aimed at the destruction of the “diseased” population. In the middle of this crossed-fire is – an infected beautiful woman – Ultraviolet, who finds herself protecting a nine-year-old boy who has been marked for death by the human government as he is believed to be a threat to humans. |

NA = 6.022 x 1023 mol-1; c = 3.0 x 108 ms-1; h = 6.63 x 10-34 J s; c = 2.998 x 108 ms-1?
1. What is the frequency of the photon of green light having a wavelength of 485 nm?
2. The green light associated with the aurora borealis is emitted by excited oxygen atoms at 557.7 nm.
What is the frequency of this light?
3. What is the energy of 1.00 mol of photons with a wavelength of 400 nm?
4. What is the energy in kilojoules of a mole of photons emitting green light having a wavelength of
485 nm?
5. What is the binding energy of an electron in a photosensitive metal in J/mol if light of the frequency
of 6.0 x 1014 s-1 impinging on the metal surface is just able to eject electrons?
6. If the energy change for the transition between the ground state and an excited electronic state is
3.85 x 105 J/mol, what is the wavelength for the photon of light necessary to induce this transition?
7. Mycobacterium tuberculosis, the organism that causes tuberculosis, can be completely destroyed by
irradiation with ultraviolet light with a wavelength of 254 nm. What is the frequency of the
radiation?
8. Radio Satu RTM, broadcasts in AM signal, a form of electromagnetic radiation, at a frequency of
1240 kHz. What is the wavelength of these radio waves expressed in metres?
9. The human ear is sensitive to sound ranging from 20 to 20,000 Hz. The sped of sound is 330 m/s in
air and 1500 m/s under water. What is the longest and the shortest wavelength that can be heard
(a) in air and (b) under water?
10. Microwaves are used to heat food in the microwave ovens. The microwave radiation is absorbed by
moisture (through absorption of rotational energy of the water molecule) in the food. This heats the
water, and as the water becomes hot, so does the food. How many photons having a wavelength of
3.00 mm would have to be absorbed by 1.00 g of water to raise its temperature by 1.00 ?C? Hint you
need to know the specific heat capacity of water!
11. How many grams of water could have its temperature raised by 5.0 ?C by a mole of photons that
have a wavelength of (a) 600 nm and (b) 300 nm?
12. It has been found that when the chemical bond between chlorine atoms in Cl2 is formed, 328 kJ is
released per mole of Cl2 formed. What is the wavelength of light would be required to break
chemical bonds between chlorine atoms?
i could only help you if you wrote it in english lol ha ha
