Unlike Earth and other solid objects, the entire Sun doesn't rotate at the same rate of gas and plasma, different parts of the Sun spin at different rates.
Electromagnetic radiation changes its wavelengths when it interacts with matter due to phenomenon such as absorption, reflection, or scattering. These interactions can cause the radiation to lose or gain energy, resulting in a shift in wavelength.
Potential difference.
A redshift occurs when the wavelengths increase in objects by light or electromagnetic radiation levels in an object. In cosmological redshift also has to do with light; however, instead of an increase in wavelengths, there is an expansion of the universe.
The atmosphere easily transmits shortwave radiation from the Sun, BUT is a poor transmitter of LONG-WAVE radiation from Earth's surface. This selective transmission causes the Greenhouse effect in the atmosphere.
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

different wavelengths from different colours
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.Light is made up of radiation of different wavelengths/frequencies; our eyes can perceive some of these differences in wavelengths/frequencies.
Ultraviolet waves of certain wavelengths kill bacteria, tan your skin, and produce the effect known as fluorescence. pg 52 of your textExamples: ultraviolet radiation, visible light.
Potential difference.
The reason behind the difference in color between purple light and red light is due to their different wavelengths. Purple light has a shorter wavelength and higher frequency, while red light has a longer wavelength and lower frequency. This difference in wavelength causes our eyes to perceive them as different colors.
Not exactly. Different colors are different frequencies of light. "Spectrum", on the other hand, refers to an analysis of a mix of wavelengths.
what is the causes of asthma
The main difference is in their wavelengths. Blue light has a shorter wavelength (~450-495 nm) compared to red light (~620-750 nm). This difference in wavelength causes them to be perceived as different colors by our eyes.
