X-rays are electromagnetic waves that can penetrate skin, but not bone. In hospitals, X-rays are used to produce images of bones. How do X-rays compare to visible light? A. X-rays have a higher frequency and carry more energy than visible light. B. X-rays have a higher frequency and carry less energy than visible light. C. Visible light has a higher frequency and carries more energy than X-rays. D. Visible light has a higher frequency and carries less energy than X-rays.

A. X-rays have a higher frequency and carry more energy than visible light.

Explanation:

A. X-rays have a higher frequency and carry more energy than visible light

Explanation:

Both x-rays and visible light are electromagnetic waves.

The amount of energy carried by an electromagnetic wave depends on the frequency of the wave. The frequency of x-rays is greater than that of visible light, so the energy carried by x-rays is also greater than that of visible light. The high frequency of x-rays allows them to penetrate skin, but they are absorbed by bone, which allows an image of the bone to be produced.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
