When the emitted light is passed through a prism, only a few narrow lines of particular wavelengths, called a line spectrum, are observed rather than a continuous range of wavelengths (Figure \(\PageIndex{1}\)). The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the ...
A continuous spectrum covers a wide range of wavelengths or frequencies, spanning from low to high energies. It includes all possible values within a given range, without any gaps. In contrast, a line spectrum consists of specific wavelengths or frequencies, with distinct gaps between them.
26 Ιουν 2023 · Differentiate between a continuous and discontinuous spectrum; Classify all types of radiation as being ionizing or nonionizing. Understand that ionizing radiation can knock electrons off DNA. Know that radiation of short wavelength is toxic. Understand the processes of absorption and emission. Explain the science behind fireworks.

1. Draw the spectra of an incandescent light bulb and of a fluorescent light bulb. 2. What’s the difference between a line spectrum and a continuous spectrum? Draw one of each.
Objective: Learn how the color of light emitted by a gas tells us the energy state of electrons in the element. Instructions: Using the vapor tubes below determine the line spectra for each of the following.
Absorption spectra. An absorption spectrum occurs when light of all wavelengths passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies.
