Doppler effect
False. The frequencies of radiation decrease as the wavelengths increase. This is because frequency and wavelength are inversely proportional in the electromagnetic spectrum.
To increase the energy of an electromagnetic wave, you should increase its frequency. Energy is directly proportional to frequency for electromagnetic waves, according to the equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
The frequency of an electromagnetic wave is inversely proportional to its wavelength, meaning a higher frequency corresponds to a shorter wavelength. The angular velocity of an electromagnetic wave is directly proportional to its frequency, so an increase in frequency will lead to an increase in angular velocity.
Objects that absorb electromagnetic radiation receive energy from the radiation in the form of heat. This increase in energy causes the atoms and molecules in the object to vibrate, which we perceive as an increase in temperature.
No. As the radiation frequency moves from left to right in the frequency spectrum, the wave speed is the same in a certain medium -- in vacuum, it is 3E8 m/s. The energy increases with frequency, though.
False. The frequencies of radiation decrease as the wavelengths increase. This is because frequency and wavelength are inversely proportional in the electromagnetic spectrum.
It will become longer, and it will carry less energy, its also likely, that if the change or loss in frequency is enough, the radiation will become a different type of electromagnetic radiation in the spectrum like gamma to x-rays or visible light to infrared and so on.

From least to greatest energy, the order would be: Infrared radiation < microwaves < blue light < orange light < X-rays This order is based on the electromagnetic spectrum, where the frequency and energy of radiation increase from left to right.
As you increase frequency past violet light, to the region where the eye no longer perceives it, you're in the "ultraviolet" region.
well electromagnetic radiation is a combination of electrical and magnetic well electromagnetic radiation is a combination of electrical and magnetic
Does the energy of a photon increase as the frequency decreases ? No.In fact it is just the opposite : energy increases as the frequency increases.The relation is very simple; it's just e=hv wheree is the energy of the photonh is Planck's constantv is the frequency of the radiation.( v should be the Greek letter nu, but this keyboard won't do it ! )
For electromagnetic radiation,c = speed of light = 3.0 x 108 m/s = frequency x wavelengthAs the frequency of light waves increase, the wavelength decreases. For electromagnetic radiation, the wavelength times the frequency equals the speed of light, c, which is 3.0 x 108 m/s. So, if the frequency increases, the wavelength will decrease, and if the wavelength increases, the frequency decreases.
As the frequency of an electromagnetic wave increases, the energy of the wave increases. This is because energy is directly proportional to the frequency of the wave according to Planck's equation (E=hf), where h is Planck's constant.
