One of the properties of electromagnetic radiation is that when viewed according to the 'particle' model, the energy carried by each particle ("photon") is proportional to its frequency. So, as you go up the spectrum in frequency (downward in wavelength), each photon carries more energy.
This is the best intuitive explanation for why a beam of radio or red light shining on a metal surface can't dislodge electrons from the metal no matter how intense the beam is, but a beam of ultraviolet light or X-ray can do it no matter how dim the beam is.

How powerful is the sun's UV rays?
The UV rays are very powerful. They can even penetrate the skin.
Why does the lymphocytes need more mitochondria?
they need more mitochondria because as we know, mitochondria is the power house and it produces energy... so, lymphocytes need more mitochondria because they need a lot of energy inorder to carry out theyre required function....
Does chicken have a lot of proteins?
All organisms have a lot of proteins, as they allow us to function.
Can gamma rays from stars be captured and turned to energy?
Yes, but not to any usable amount. The amount of energy that comes from gamma rays bursts are, by the time they reach here, quite small. The INTENSITY of the bursts may be large, but they don't last very long. Also, they come from outside our galaxy, so they have lost most of their energy by the time they get to us. And the direction they arrive from is impossible to predict, so any collector would be impossible to aim for maximum efficiency. If a ten meter by ten meter collector was 100% efficient in converting gamma ray energy into electricity, and was able to collect enough energy from gamma rays to power a 100 watt light bulb for ten minutes; the amount of gamma ray energy hitting our Earth would kill all humanity in less than a week. In a sense, it is a blessing that there is not a lot of gamma ray energy reaching us!
What do your energy points do in khan academy?
Energy points are only really useful when you get a lot of them. For example one way to get a Sun Badge is to earn 500,000 energy points. That's a lot of energy points!
Which type of rays from the sun have a lot of heat and energy?
sun's rays
Do light waves carry energy?
Light waves do carry energy, and when oscillated light can carry information.
Does microwave radiation carry a lot of energy?
It can do certainly. In a microwave oven there is enough energy to heat food quickly
What type of radiation do O3 molecules absorb?
The ozone molecule actually does not absorb any kind of radiation. Since it does not allow the UV rays to pass thus it was thought that it absorbs the UV rays but actually a process is ongoing in the ozone layer which uses all the ultraviolet rays. Actually the process of formation and depletion of ozone requires a lot of energy which is provided by the UV rays and thus the formation and depletion of ozone takes place because of these rays
what TYPE of animal cell that has a lot of mitochondra?
Cells that require a lot of energy to carry out their functions, such as muscle cells and nerve cells, tend to have a high concentration of mitochondria. Muscle cells, for example, require a lot of energy to contract and relax, so they have a high density of mitochondria to produce the ATP (adenosine triphosphate) required for energy. Similarly, nerve cells require a lot of energy to transmit signals along their length, so they also have a high concentration of mitochondria. Other cells that have a high density of mitochondria include liver cells, which have a lot of metabolic processes, and kidney cells, which require a lot of energy to carry out their filtration function.
Do photons of blue light have more or less energy than photons of red light?
Photons of Blue light have more energy than photons of red light. Ultraviolet have even more, x rays yet more, gamma rays still more, and some cosmic rays still a lot more. Infrared have less, and radio waves have less, and other waves have even less.
Which process is required to allow a gravitationally-collapsing gas cloud to continue to collapse?
The cloud must radiate a lot of its thermal energy.
Difference between hard and soft x-rays?
The difference between a hard x-ray and a soft x-ray is the amount of energy that they both use. Hard x-rays are used to see the inside of the human body. Soft x-rays are not used often because they omit a lot of radiation.
Why is radiation referred to as electromagnetic?
Though not all radiation is electromagnetic, a lot of it is. Sound, which is mechanical energy, can radiate. It is a type of radiated energy. There are others. But radio waves, microwaves, light, X-rays and gamma rays are all forms of electromagnetic energy. The only difference is the frequency or energy of the radiation (and we lined them up for you from lower frequency to higher frequency). The universe is awash is electromagnetic energy. It's all around us. Use the links below to learn more.
What is the difference between radio waves and gramma waves?
The wavelength of radio waves are on the magnitude of 10^4 meters, while gamma rays have a far shorter wavelength of around 10^-14. This implies that gamma rays carry a lot more energy than radio waves, due to their frequency being much higher than that of radio wave frequencies.
Does nuclear energy use a lot of energy?
No, the opposite, it releases a lot of energy
How do solar fountains work?
A solar fountain gets energy from the rays that the sun produces. You just need to put it in an area that has a lot of sun and then you will be able to use it without using electricity!
