|
All forms of electromagnetic radiation have the same amount of energy in a vacuum

Detailed explanation-1: -Electromagnetic radiation is energy that travels in waves. Some examples of electromagnetic radiation are visible light, radio waves, and x-rays. Which statement is true for all forms of electromagnetic radiation? All forms of electromagnetic radiation travel at the same speed in a vacuum.
Detailed explanation-2: -Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices.
Detailed explanation-3: -Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.
Detailed explanation-4: -Answer and Explanation: From the choices, the incorrect statement is E) x-rays have longer wavelengths than radio waves, E) x-rays have longer wavelengths than radio waves, because radiowaves have longer wavelengths than x-rays.
Detailed explanation-5: -Radiant energyis energy that travels by radiation. An example of this is light.
