Q.1. The increasing order of energy is
Red < Green < Blue
The pattern of colour wheel is VIBGYOR
Where V - violet, I - indego, B - blue, G - green, Y - yellow, O - orange, R - red
Red colour has highest wavelength with lowest energy
And Violet colour has lowest wavelength with highest energy.

Measured Wavelength for Hg vapor
> 900 3. A student used a Measured Wavelength (nm) vs. Actual Wavelength (nm) for Hg Vapor spectroscope to view the emission spectrum of Hg vapor, and plotted her measured wavelengths ly- axis) vs. the actual wavelengths (x-axis). The actual wavelength of the most prominent line in the emission spectrum of Na is 589 nm. If the spectroscope used to prepare the calibration curve is used to view the emission spectrum of Na, what wavelength...
