First, the energy emitted at every wavelength is higher for the hotter star. Secondly, the peak wavelength of the hotter star is shorter than that of the 4000K one.
Ionizing radiation is produced by unstable atoms. Unstable atoms differ from stable atoms because they have an excess of energy or mass or both.
they are differ by their color they are also differ in temperature
There are only two types of radiation. 1. Electromagnetic Under this we have gamma radiation, X radiation, light and heat 2. Particle radiation Under this we have alpha and beta.
Stars differ with its shape.Also how are stars are brighter than others
Electromagnetic radiation is the fastest known information carrier, and according to relativity and modern physics, it's the fastest possible. The term 'electromagnetic radiation' includes AM and FM radio, TV, microwave radio, microwave cooking rays, heat, visible light, ultraviolet, X-rays, and several others. All of these are the same physical phenomenon; they differ only in wavelength (frequency), and they all travel at the "speed of light" ... about 300 million km (186 thousand miles) per second.
what r u on about
I have no clue Laugh out loud
Those are three different means by which heat can travel. In convection, heat is carried by moving matter. In conduction, heat is transferred by means of a physical contact between two objects of different temperature. With radiation, energy is emitted in the form of electromagnetic radiation, usually in the infrared spectrum.

In the spectrum of electromagnetic radiation the wave property that changes is the frequency. So for example xrays have higher frequency then blue light which has higher frequency then red light which has higher frequency then radio waves etc.
Temperatures, as provided by thermometers, measure and quantify the extent of thermal changes.
temperatures differ from thermal energy because differ because thermal energy is the total energy of all particles in an object and temperature is a measure of the average energy of random motion of particles of matter.
A molecule has additional spectral lines due to changes in its rotational and vibrational energies.
In fact, radiations are reflected by earth but not emitted.
They differ:* By their frequency * By their wavelength, which is inversely proportional to their frequency * By the energy per photon, which is proportional to the frequency
Cosmic microwave background radiation was predicted by Big Bang Cosmology about 16 years before the former was discovered -- by accident. The existence, isotropy, and spectrum of CMBR are all exactly as predicted by BBC, and all alternatives to BBC are reduced to stating, "It's just there and there is absolutely no explanation for it."
