Order the following frequency ranges from lowest energy to highest energy.
Gamma,
ultraviolet,
FM radio,
Visible,
Infrared,
Microwave,
Cell phone,
x-rays
To determine the order of frequency ranges from lowest energy to highest energy, you need to understand that energy is inversely proportional to the wavelength. The shorter the wavelength, the higher the energy, and vice versa. Therefore, we can arrange the frequency ranges in order of decreasing wavelength, which corresponds to increasing energy.
Here is the order of the given frequency ranges from lowest energy to highest energy:
1. Radio waves (FM radio and cell phone): Radio waves have the longest wavelengths and lowest energy among the options provided.
2. Microwave: Microwaves have slightly shorter wavelengths compared to radio waves and slightly higher energy.
3. Infrared: Infrared waves have shorter wavelengths and higher energy than microwaves.
4. Visible light: Visible light is the range of electromagnetic radiation that is visible to the human eye. It has a medium wavelength and energy level compared to the other options.
5. Ultraviolet: Ultraviolet waves have shorter wavelengths and higher energy than visible light.
6. X-rays: X-rays have even shorter wavelengths and higher energy than ultraviolet waves.
7. Gamma rays: Gamma rays have the shortest wavelengths and highest energy among the options provided. They are highly penetrating and can be dangerous in high doses.
So, the order from lowest energy to highest energy is:
FM radio < Cell phone < Microwave < Infrared < Visible < Ultraviolet < X-rays < Gamma.
