Which object emits the radiation at the shortest wavelengths?

Which object emits the radiation at the shortest wavelengths?

Electromagnetic radiation with the shortest wavelengths, no longer than 0.01 nanometer, is categorized as gamma rays (1 nanometer = 10–9 meters; see Units Used in Science).

What determines the type of radiation emitted by an object?

All objects with a temperature greater than absolute 0 emit electromagnetic radiation, which is commonly called the object’s thermal emission. The temperature of the radiating body determines the intensity and characteristics of the radiation it emits.

Is radiation affected by temperature?

All objects actually emit radiation if their temperature is greater than absolute zero. This law (expressed mathematically as E = σT4) states that all objects with temperatures above absolute zero (0K or -273°C or -459°F) emit radiation at a rate proportional to the fourth power of their absolute temperature.

At what temperature does radiation become important?

1000 K

What can you do to protect yourself from this radiation?

Staying inside will reduce your exposure to radiation.

1. Close windows and doors.
2. Take a shower or wipe exposed parts of your body with a damp cloth.
3. Drink bottled water and eat food in sealed containers.

Which of the following reason does not affect radiation between two parallel bodies?

Which of the following reason does NOT affect radiation between two parallel bodies? Explanation: The angle of vision does not affect radiation between two parallel bodies. But, it is an important factor when it comes to curved surfaces.

What is the rule of radiation to energy?

The total radiant heat energy emitted by a surface is proportional to the fourth power of its absolute temperature (the Stefan–Boltzmann law). As a rule of thumb, approximately 35 percent of the total energy yield of an airburst is emitted as thermal…

Which of the following is the best example of radiation?

Radiation Examples

• ultraviolet light from the sun.
• heat from a stove burner.
• visible light from a candle.
• x-rays from an x-ray machine.
• alpha particles emitted from the radioactive decay of uranium.
• sound waves from your stereo.
• microwaves from a microwave oven.
• electromagnetic radiation from your cell phone.

What is non example?

A non-example would be a word that is not an example of a bird. It is important to come up with non-examples that are related to the word, but that are not examples of the word.

Is a microwave an example of radiation?

Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.
