The answer is a traveling wave
Travelling waves are temporary waves and these occur for a very short duration and move with constant speed. It is represented by an infinite rectangular waves. The crest of travelling wave move in wave propagating direction. Mathematically a periodic travelling wave is a one dimensional space that moves constantly with unvarying velocity through some medium.
Using E=hν where h is Planck's constant and v is the frequency of the photon. In the question above,the wavelenght is given so we can find the frequency of the photon using c=λν. c is a constant =3*10^8 so frequency is equal to
(3*10^8)/0.135*10^-9. Then use ur frequency in the eqn above using h 6.626*10^-34
Answer:
Hydropower
Explanation:
I learn whenever Hydro is in a word it means water
Also in the question it is talking about water and wind, solar, nor Biomass has anything to do with water, so you can use the process of elimination and find you will only have Hydropower left.
Hope this helps
H2O is classified as water.
