Electromagnetic waves of the longest wavelength carry the greatest energy?
No. The energy of an EM wave is E = h*c / (wavelength), therefore waves with the shortest wavelength (or highest frequency) carry the greatest energy.
How is wavelength of an EM wave related to its energy?
The shorter the wavelength of a wave, the higher its energy.
What does the wavelength of a EM wave tell you about its energy?
It tells you that the longer the wavelength the lower the energy. From the wavelength, one can also calculate the actual energy by using E = cxh/lambda where c is speed of light, h is Plank's constant and lambda is the wavelength.
Which type of em spectrum has the highest wavelength?
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
What does the wave length of an EM wave tell about its energy?
Longer wavelength less energy and shorter wavelength equals more energy. This is because velocity (speed)=frequency x wavelength. And te velocity of all EM waves is the speed of light. we know the expression- frequency=speed of light(c)/wavelength Energy is given by- E=h*frequency=h*c/wavelength {h=Planck's constant} so,energy is directly proportional to frequency and inversly proportional to wavelength...that is energy increases with increase in frequency and decreases with increase in wavelength. example:-red color has more wavelength and hence has less energy.

No. The energy of an EM wave is E = h*c / (wavelength), therefore waves with the shortest wavelength (or highest frequency) carry the greatest energy.
What are facts for radio waves?
Radio waves have the longest wavelength in the electromagnetic spectrum (EM), and are pure energy, they have no mass.
What type of em radiation has shortest wavelength and most energy?
Gamma radiation
What does the wavelength of an em tell about it's energy?
As the wavelength decreases, the energy increases.
What type of EM radiation has the shortest wavelength and the most energy?
gamma rays
How is wavelength of an EM wave related to its energy?
The shorter the wavelength of a wave, the higher its energy.
Which type of EM waves has the longest wavelenght?
Extremely low frequency (ELF) waves have wavelength of the order of 100 megametres ( = 100,000 kilometres).
Which EM region has the longest wavelength?
Radio Waves. Their wavelength is 103 meters (1 kilometer). Because of this, their waves have the lowest frequency.
What does the wavelength of EM wave tell you about its energy?
It tells you that the longer the wavelength the lower the energy. From the wavelength, one can also calculate the actual energy by using E = cxh/lambda where c is speed of light, h is Plank's constant and lambda is the wavelength.
