The energy of microwaves is less than the energy of ultraviolet light. which comparison of the energies of electromagnetic waves is correct?
a. x-rays have lower energy than gamma rays because x-rays have higher frequencies.
b. x-rays have lower energy than gamma rays because x-rays have shorter wavelengths.
c. visible light has higher energy than infrared light because visible light has longer wavelengths.
d. visible light has higher energy than infrared light because visible light has higher frequencies.

The correct answer is option D.

Explanation:

The energy(E) of the electromagnetic waves is given by:

=  frequency of the electromagnetic wave.

= wavelength of the electromagnetic wave.

The order of electromagnetic spectrum from highest frequency to lowest frequency is :

γ-rays> X-rays> UV-rays>Visible Light>Infrared>microwaves>Radio waves.

From the spectrum, the frequency of the visible light is higher than that of the infrared rays. Higher the frequency higher will be the energy of the wave.Hence option D is a correct answer.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
