A neon lamp produces what kind of visible spectrum?

1) A neon lamp produces what kind of visible spectrum?

2) The particle of light emitted when at atom changes from a higher energy level to a lower energy level is called

3) The wavelength of blue light is greater than red light and its energy is greater. True or False?

4) In the grating equation n?=d sin ?, the quantity ? will be determined in the lab?

5) The study and analysis of light according to its component wavelengths is called?

Expert Solution

1) Discrete: Neon light emits wavelengths specific to the atoms in the bulb with little or no wavelengths in between.

2) Photon

3) False because, Blue light has a smaller wavelength, higher energy, while red light has a longer wavelength with lower energy.

4) "using meter sticks and geometry/trigonometry".

5) spectroscopy

(a) A helium lamp is used for an experiment to study the photoelectric effect. The visible part of the spectrum emitted from the lamp is split into its components using a glass prism, which reveals a yellow spectral line at 587nm and a blue spectral line at 447nm. (i) Explain briefly the origin of the distinct lines of different colour. (ii) Has blue or yellow light higher energy (per photon)? Justify your answer. (iii) The refractive index of the glass...

1) The emission spectrum of a hollow cathode lamp for molybdenum was found to have a sharp peak at 313.3 nm as long as the lamp current was less than 50 mA. At higher currents, however, the peak developed a cup-like crater at its maximum. Explain. 2) Why does the cathode of the hollow cathode lamp have a cylindrical shape? Why is an element lamp required as the source for AA? Which copper line was used for analysis of copper...

1. What Region of visible light spectrum yields the highest photosynthetic rates in spinach? What regions yield the lowest photosynthetic rates? How do you know? (See graph below) 2. 2. Green photosynthetic pigments (e.g., chlorophyll a and b) capture energy from a wide—but not the widest possible—region of the visible spectrum of light. What pigment color would enable plants to capture energy from almost the entire spectrum of visible light? Why, then, are most plants green? (see graph below) 3....
