Which one of the following sources produces the highest energy photons? A)a doctor's x-ray source B)a heat lamp in a restaurant C)a microwave oven D) gamma rays from a star radio E)waves from a local station

Answers

Answer:D) Gamma rays

Explanation:

Energy of a photon= h( Planck constant) * f (frequency)

So we take a look at the electromagnetic spectrum i am attaching and see which wave will have the highest frequency.  

As a note frequency is inversely proportional to wavelength so highest energy is also shortest wavelength.  

Therefore the highest energy are gamma rays

Hope this helps

Final answer:

Among the options provided, gamma rays from a star radio produce the highest energy photons. This is due to the larger energy differences in gamma rays. The radiation emitted by a microwave oven, a heat lamp, local station waves, or a doctor's X-ray are of lesser energy comparatively.

Explanation:

The source that produces the highest energy photons among the options provided is 'gamma rays from a star radio'. This is because gamma rays are part of the electromagnetic spectrum and known for having short wavelengths and high energy. In fact, the energy of gamma rays is much larger than the energy released by a microwave oven, a heat lamp, radio waves from a local station or even a doctor's X-ray machine.

Nuclear energy shells in gamma rays have energy differences that are millions of times larger than electromagnetic radiation from electronic transitions. In contrast, examples like a microwave oven work with much smaller energy scales, producing electromagnetic radiation that is absorbed by water molecules, leading to an increase in the molecules' rotational energies.

Microwaves and heat lamps emit infrared radiation, doctors use X-rays, and local stations emit radio waves. However, none of these have as much energy as gamma rays, which can be produced in stars, among other places. Gamma rays are the most energetic form of light and are created by the hottest and most energetic objects in the universe, such as stars and black holes.

The temperature scale which starts at absolute zero is the _____.Centigrade scale
Celsius scale
Fahrenheit scale
Kelvin scale

Answers

The temperature scale which starts at absolute zero is the Kelvin scale. The correct option in respect to the given question is the last option. William Thompson was the British scientist and inventor that invented the Kelvin scale. William Thompson was also popularly known as Lord Kelvin.His discovery of the Kelvin scale is considered one among the three best scales in use for measuring temperatures.Each measuring unit of this scale is never called a degree but a Kelvin. This specialized scale gives the option of measuring temperature in both centigrade and Fahrenheit.
the temperature that the scale starts at absolute zero is called the Kelvin scale
