Unit 11A - Radiant Energy Waves

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, which can travel through space and carry energy from one place to another.

Front

What is wavelength?

Back

Wavelength is the distance between successive peaks of a wave, typically measured in meters.

Front

Which type of radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength among all types of electromagnetic radiation.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What type of radiation is visible to the human eye?

Back

Visible light is the type of radiation that can be seen by the human eye.

Front

What is ultraviolet light?

Back

Ultraviolet light is a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, ordered by wavelength or frequency.

Front

What type of radiation has a longer wavelength than visible light?

Back

Infrared light has a longer wavelength than visible light.

Front

What is blue light?

Back

Blue light is a type of visible light with a wavelength between approximately 450 and 495 nanometers.

Front

What is the significance of gamma rays?

Back

Gamma rays are significant because they have the highest energy and shortest wavelength in the electromagnetic spectrum, making them useful in medical treatments and imaging.
