Answer:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Explanation:
Materials when heated emit a continuous spectrum with all wavelengths.
Hot gas gases emit a spectrum that depends on the transitions between atomic states, therefore it is a discrete spectrum.
When reviewing the answers, the correct one is:
ncandescent solids emit continuous spectra; incandescent gases emit bright-line spectra.
Answer:
n = 1.42
Explanation:
The refractive index for a medium is given by the ratio of the speed of light in vacuum to the speed of light in a medium.
So, the refractive index of the medium is 1.42.
= Joules ÷ (0.5×Kilograms)
14J ÷ 8.5 = 1.64705882
Remember, 1.64705882 = v², so we need to find the square root.
The square root of 1.64705882 is 1.283377894464448
