All parts of the electromagnetic spectrum share travel at the same speed through empty space.
True
False

The statement is true that all parts of the electromagnetic spectrum share travel at the same speed through empty space.

Explanation:

Electromagnetic spectrum is the word given to all the light waves that exist. Light is the form of energy that shows both the character of electricity and magnetism. Hence called as the electro-magnetic spectrum.These electromagnetic spectrum always travel in a speed equal to speed of light which is approximately 300 million m/s in the empty space. Only electromagnetic wave can travel in the vacuum i.e. empty space

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
