The bright red color in fireworks is due to emission of light when Sr(NO3)2 is heated. If the wavelength is 650.0 nm, what is the frequency of this light?
Homework Answers
For a given wavelength of light:
Frequency of the light= Velocity of light / wavelength of the light.
Velocity of light= 3 ×108m/s
Given wavelength = 6.5 × 10-7m
Frequency = 3×108 / 6.5 × 10-7 s-1
= 4.6 × 1014 s-1

Quantitative Section 6. The brilliant red colors seen in fireworks are due to the emission of light with wavelengths around 650 nm when strontium salts such as Sr(NOs)h and SrCO are heated. (This can be easily demonstrated in the lab by dissolving one of these salts in methanol that con- tains a little water and igniting the mixture in an evaporating dish ) Calculate the frequency of red light of wavelength 6.50 X 10 nm.

The red color in some fireworks is due to the presence of strontium metal. In the firework, strontium metal combine with carbon in the form of graphite and oxygen gas to produce strontium carbonate. The formation of one mole of strontium carbonate releases l.220 times 10^3 kJ of energy. How much energy, in kJ, is generated from the formation of 1.95 g of strontium carbonate?

You are using a hydrogen discharge tube and high quality red and blue light filters as the light source for a Michelson interferometer. The hydrogen discharge tube provides light of several different wavelengths (colors) in the visible range. The red light in the hydrogen spectrum has a wavelength of 656.3 nm and the blue light has a wavelength of 434.0 nm. When using the discharge tube and the red filter as the light source, you view a bright red spot...
