Explanation:
It is given that,
Wavelength 1,
Wavelength 2,
Energy of a photon having wavelength 1 is given by :
Energy of a photon having wavelength 2 is given by :
Hence, this is the required solution.
Answer:
Chemical changes are also known as chemical reactions. The “ingredients” of a reaction are called reactants, and the end results are called products.
Explanation:
<span>The relationship between a cathode and an anode involves:
</span>
A. electrons.
Negatively ions which have excess electrons move to the Anode, while Postively charged ions which have less electrons move to the Cathode.
It has increased. More kinetic energy increases the opposing force.
