Which waves in the electromagnetic spectrum are considered low energy waves?

sound waves and light waves
gamma rays and x–rays
microwaves and sound waves
radio waves and microwaves

Radio waves and microwaves

Explanation:

The energy of a wave is given by :

.........(1)

The wave having low frequency or high wavelength will have low energy. The wavelength of radio wave and microwave is maximum in the electromagnetic spectrum.

From equation (1) it is clear that the energy is wave is inversely proportional to the wavelength. If the wavelength is high, it will have low energy. So, the correct option is (d) "radio waves and microwaves".

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

this is poiselle's equation from fluid mechanic in physics. mech eng
