Chemistry 121 Chapter 6 Part 1

Explanation
Wavelength refers to the distance between two consecutive crests or troughs in a wave. It is a measure of the length of one complete cycle of a wave. In the context of the question, the distance between two crests is being referred to, which aligns with the definition of wavelength. Absorption and frequency do not directly relate to the distance between crests, making them incorrect choices.

Explanation
Frequency refers to the number of oscillations or cycles that occur per second. It is a measure of how often a wave, such as a sound wave or electromagnetic wave, repeats its pattern. In the context of the given options, frequency is the correct answer as it directly relates to the number of oscillations per second. Wavelength, on the other hand, refers to the distance between two corresponding points on a wave, while electrons are subatomic particles that carry a negative charge.

Explanation
The given correct answer is Planck Equation. The Planck Equation, also known as Planck's law, is a fundamental equation in physics that describes the relationship between the energy of a photon and its frequency. It is used to calculate the energy of a photon, which is given by the equation E = hf, where E is the energy, h is Planck's constant (6.63 x 10^(-34) J·s), and f is the frequency of the photon. This equation is crucial in understanding the behavior of electromagnetic radiation and the quantization of energy.

Explanation
Electrons are subatomic particles that are found in orbits around the nucleus of an atom. These orbits, also known as energy levels, determine the position and movement of electrons within an atom. Electrons can only move in specific orbits, also called shells, and they can jump between these energy levels by either absorbing or emitting energy. This process is known as absorption or emission of photons, which allows electrons to transition between different energy levels within an atom. Therefore, electrons are the correct answer to the given statement.

Explanation
Electrons have a negative charge and are located in energy levels around the nucleus of an atom. Moving away from the nucleus requires energy because the attractive force between the positively charged protons in the nucleus and the negatively charged electrons must be overcome. As electrons move to higher energy levels, they gain energy, and as they move to lower energy levels, they release energy. Therefore, it takes energy for electrons to move away from the nucleus.

Explanation
Electrons give away energy when moving towards the nucleus. This is because as electrons move closer to the positively charged nucleus, they experience a stronger attraction. This attraction causes the electrons to lose energy, which can be released in the form of electromagnetic radiation or heat. This phenomenon is known as electron energy release or electron energy transition.

Explanation
Atoms are the correct answer because they are the fundamental building blocks of matter. When atoms decay or undergo a process called radioactive decay, they release energy in the form of radiation, which can include light. This release of energy occurs due to the unstable nature of certain atoms, which strive to achieve a more stable state by emitting radiation. Therefore, atoms are responsible for the phenomenon of decay and the subsequent release of energy that produces light.

Explanation
Absorption refers to the process where light or electromagnetic radiation is absorbed by a material. In this context, the statement suggests that all colors of the spectrum are being absorbed by the material. This means that the material is capable of absorbing all wavelengths of light, resulting in the absence of any color being reflected or transmitted.

Explanation
Emission refers to the process in which energy is released in the form of electromagnetic radiation, such as light. In the context of the given statement, it suggests that only the line segments of the spectra are emitted, indicating that specific wavelengths or frequencies of light are being emitted. This is in contrast to absorption, which involves the absorption of light or energy, and wavelength, which refers to the distance between two corresponding points on a wave.
