Electrons and Light Practice

Front

What is the color of visible light with the LONGEST wavelength?

Back

Red

Front

Calculate the energy of a photon with a frequency of 5.0 x 10^14 Hz using E = hv (h = 6.626×10^−34 J*s).

Back

3.3 x 10^-19 J

Front

What does an orbital represent in an atom?

Back

The most probable location of an electron.

Front

Which wave has the shortest wavelength: radio waves, visible light, or gamma rays?

Back

Gamma rays.

Front

Which wave has the most energy: radio waves, visible light, or gamma rays?

Back

Gamma rays.

Front

Define wavelength in the context of electromagnetic waves.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is Planck's constant?

Back

Planck's constant (h) is 6.626 x 10^-34 J*s.

Front

What is the formula to calculate the energy of a photon?

Back

E = hv, where E is energy, h is Planck's constant, and v is frequency.

Front

What is the visible spectrum?

Back

The visible spectrum is the range of wavelengths of light that can be seen by the human eye, approximately 400 to 700 nm.
