What else can I help you with?
Do electrons in stationary states emit the most radiation?
No, electrons in stationary states do not emit radiation because they are in stable energy levels. Radiation is emitted when electrons transition between energy levels, releasing photons of specific energies.
Why a static charge does not emit radiation?
A static charge does not emit radiation because it does not involve the accelerating or decelerating motion of charged particles, which is necessary to produce electromagnetic radiation. In a static charge situation, the charges are stationary or in constant motion, so there is no changing electric or magnetic field to generate radiation.
Which two of the following planets do NOT give off more radiation than they receive from the Sun?
The following means that you have to give choices.
Why are Niels Bohr orbits called stationary state?
Niels Bohr called the orbits "stationary states" because in these states, electrons do not emit electromagnetic radiation or lose energy, resulting in stable orbits. These stationary states are characterized by specific energy levels, and transitions between these states result in quantized energy exchanges. This concept helped explain the stability of the atom and laid the foundation for quantum mechanics.
Which of the following is an example of heat transfer by radiation A. an electric space heater warming a room B. a fire warming a group of campers C. the Sun warming the Earth?
Radiation is when heat shoots out like a ray, so all the examples given show radiation.
Do electrons in stationary states emit the most radiation?
No, electrons in stationary states do not emit radiation because they are in stable energy levels. Radiation is emitted when electrons transition between energy levels, releasing photons of specific energies.
Do electrons emit radiation only when in stationary states?
no, only when accelerated
Which of the following substances absorbs UV radiation?
The substance that absorbs UV radiation is ozone.
Which of the following is not considered a route of entry?
radiation
Why a static charge does not emit radiation?
A static charge does not emit radiation because it does not involve the accelerating or decelerating motion of charged particles, which is necessary to produce electromagnetic radiation. In a static charge situation, the charges are stationary or in constant motion, so there is no changing electric or magnetic field to generate radiation.
Which two of the following planets do NOT give off more radiation than they receive from the Sun?
The following means that you have to give choices.
Which of the following types of electromagnetic radiation has the longest wavelength?
Radio waves have the longest wavelength among the types of electromagnetic radiation listed.
Which one of the following types of electromagnetic radiation causes certain substance to floursce?
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
Parameters that affect the absorbed dose of radiation include which of the following?
All answers are correct.
Heat energy from the Sun is transferred to Earth primarily by which of the following processes?
Heat energy from the Sun is primarily transferred to Earth through radiation. The Sun emits electromagnetic radiation, which travels through space and reaches Earth, providing the planet with heat and light.
Which of the following is not a component of the radiation emitted by a radioactive sample a.alpha radiation b.delta radiation c.gamma radiation d.beta radiation?
Radioactive substances can emit alpha particles, gamma radiation (gamma rays) and beta radiation (beta particles). What they do not emit is delta radiation.It causes transmutation.It has a mass of 4 amus.
What therapy is always recommended after a lumpectomy?
Radiation therapy is almost always recommended following a lumpectomy.
