Question

Differences between line spectrum and band spectrum

Answer 1

Explanation:

Line spectra are also called atomic spectra because the lines represent wavelengths radiated from atoms when electrons change from one energy level to another. Band spectra is the name given to groups of lines so closely spaced that each group appears to be a band, e.g., nitrogen spectrum.

Answer 2

Answer:

solar spectrum is

a) continuous

b) line spectrum

c) spectrum of black lines

d) spectrum of black bands

Explanation:

modern periodic table is based on the atomic number of elements,what was the experiment which proved the significance of atomic number from the following

1)mullikan's oil drop experiment

2)moseley's work on x-ray spectra

3)Bragg's work on X-ray diffraction

4)discovery of x-rays by rongten
