How is global warming affected by the relative transparencies of the atmosphere to long and short wavelength electromagnetic radiation?
Global warming is influenced by the atmosphere's varying transparency to different wavelengths of electromagnetic radiation. Short-wavelength radiation from the sun, such as ultraviolet and visible light, can easily penetrate the atmosphere and reach the Earth's surface. However, long-wavelength radiation, primarily infrared emitted by the Earth, is less transparent to greenhouse gases, which trap this heat and prevent it from escaping back into space. This difference in transparency contributes to the greenhouse effect, leading to an increase in global temperatures.
What type of radiation do stars emit?
Stars emit various types of radiation, including visible light, ultraviolet radiation, and infrared radiation. They also emit X-rays and gamma rays. The type of radiation emitted depends on the temperature and composition of the star.
How do the properties of long-lived stars compare to those of short-lived stars?
Long-lived stars are typically lower in mass, shine less brightly, and have longer lifespans compared to short-lived stars. Short-lived stars tend to be more massive, burn through their fuel more rapidly, and have shorter lifespans before evolving or ending in a supernova explosion.
Are some stars about as small as earth is?
Yes, there are some stars as small as earth. It depends, however, on where the stars are located and how long they have been burnt out.
What is the difference between uv-c uv-a and uv-b?
U.V can be separated according to its energy level and wavelength with UVa having the lowest energy and longest wavelength followed by UVb and ultimately UVc which has the shortest wavelength and highest energy level. You may be familiar with UVa and UVb as the part of the suns rays which cause tanning, aging, and skin cancer. The Sun also emits UVc the most powerful and dangerous type of U.V., fortunately for us most of this is stopped in the upper atmosphere by gasses like ozone.
How does long wavelength radiation contribute to the greenhouse effect?
Long wavelength radiation, such as infrared radiation, is emitted by Earth's surface after absorbing solar radiation. Greenhouse gases in the atmosphere trap this long wavelength radiation, leading to a warming effect known as the greenhouse effect. This process helps regulate Earth's temperature by keeping the planet warm enough to support life.
What type of long wavelength radiation fills space?
Electromagnetic radiation, such as radio waves, microwaves, and infrared waves, fills space as long wavelength radiation. These forms of radiation have lower frequencies and longer wavelengths compared to visible light.
What are the wavelength's of electromagnetic radiation?
The wavelengths of electromagnetic radiation extend from any long wavelength, withno upper limit no matter how long, continuously through all possible wavelengths, withno gaps, down to any short wavelength, with no lower limit no matter how short.
Which type of radiation from the sun is the longest wavelength?
Radio waves are at the long wavelength end of the sun's emissions.
Long wavelength and a low frequency is what type of radiation?
This type of radiation would be classified as radio waves. Radio waves have long wavelengths and low frequencies, making them suitable for communication and broadcasting purposes.
What does it mean for something to have wavelike properties?
Waves are characterized by wavelength, frequency, and speed. Wavelength is the distance between two consecutive peaks or troughs in a wave. The frequency is defined as the number of waves (cycles) per second that pass a given space. Since all types of electromagnetic radiation travel at the speed of light, short-wavelength radiation must have a high frequency and long-wavelength radiation must have a low frequency.
Is long wave heat radiation given off by the earth when the earth absorbs short wave radiation?
Yes, long-wave heat radiation is given off by the Earth as it absorbs short-wave radiation from the Sun. This process is known as the Earth's energy balance, where incoming solar radiation is absorbed by the Earth's surface and later re-emitted as long-wave heat radiation.
What is the most destrucive fore in the universe?
Entropy - it wears everything down, ultimately converting it to long wavelength heat radiation.
What is the electromagnets?
By analogy with the spectrum of visible light from violet to red, with colours ordered in increasing wavelength, the electromagnetic spectrum is the collection of all types of electromagnetic radiation ordered by increasing wavelength. EM radiation that we can detect runs from ultra-long wavelength radio waves used to communicate with submarines, through long-wave, short-wave, VHF and UHF radio to microwaves, infra-red (heat radiation), visible light, UV, X-rays and gamma rays.
Does the sun give off short or long wavelengths?
The sun gives off a range of wavelengths, including both short and long wavelengths. The majority of the sun's energy is in the form of visible light, which falls in the mid-range of the electromagnetic spectrum. However, the sun also emits shorter wavelength ultraviolet radiation and longer wavelength infrared radiation.
When a wave has high frequency is the wavelength short or long?
When a wave has high frequency, the wavelength is short. This is because frequency and wavelength are inversely proportional in waves. A higher frequency means more waves pass a given point in a given time, resulting in shorter wavelengths.

Global warming is influenced by the atmosphere's varying transparency to different wavelengths of electromagnetic radiation.
