Hello!
Using the equation for the electric field produced by a source charge:
E = Electric Field Strength ( 2.86 × 10⁵ N/C)
k = Coulomb's Constant ( 8.99 × 10⁹ Nm²/C²)
q = Charge of source charge (3 μC = 0.000003 C)
r = distance of test charge from source charge (m²)
We can rearrange the equation to solve for distance to make plugging in values easier. (Isolate for 'r').
Plug in the given values.
Answer:
Wavelength, frequency and the photon energy changes as the one goes across the ranges of the electro-magnetic radiations.
Explanation:
Electro-magnetic radiations may be defined as the form of energy that is radiated or given by the electro-magnetic radiations. The visible light that we can see is the one of the electro-magnetic radiations. Other forms are the radio waves, gamma waves, UV rays, infrared radiations, etc.
The wavelength of the radiations decreases as we go from a. radio waves -- b. infrared radiation -- c. visible light -- d. ultraviolet radiation -- e. gamma radiation.
The frequency of the radiations increases when we move from a. radio waves -- b. infrared radiation -- c. visible light -- d. ultraviolet radiation -- e. gamma radiation.
The photon energy of the radiations increases when we move from a. radio waves -- b. infrared radiation -- c. visible light -- d. ultraviolet radiation -- e. gamma radiation.
