Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
Violet light has the highest energy.
Every element has a unique emission spectrum. The lines in these spectra deduce the amount of energy released during electron transition from a higher energy level to a lower. After obtaining this spectrum, the scientists can compare them with their tabulated data.
electromagentic energy.
Electromagnetic
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
a broader spectrum of visible light energy can be used for photosynthesis
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.

exactly what you said its called visible light.
Yes. Light is an electromagnetic wave. Light is a very narrow band in the electromagnitc spectrum.
When a star is blue it means it is putting out light mostly in the ultraviolet spectrum which is of a higher energy than infared light, or light in the visible spectrum. This means the star has more energy and heat.
