Ch 5 - Flashcard Ch 5.1 - Light and Quantized Energy

Front

What is the relationship between wavelength (λ) and frequency (ν)?

Back

Wavelength (λ) and frequency (ν) are inversely proportional.

Front

What are photons?

Back

Photons are the particles that make up light, according to the particle model.

Front

What is the speed of red light in a vacuum?

Back

The speed of red light in a vacuum is 3.00 x 10^8 m/s.

Front

What type of spectra do we observe when viewing element tubes through diffraction gratings?

Back

We observe bright line spectra.

Front

Which of the following does not necessarily describe a wave?

Back

The answer is 'c'.

Front

Define wavelength in the context of light.

Back

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

Front

Define frequency in the context of light.

Back

Frequency is the number of wave cycles that pass a point in one second, measured in hertz (Hz).

Front

What is the formula that relates the speed of light (c), wavelength (λ), and frequency (ν)?

Back

The formula is c = λν, where c is the speed of light.

Front

What is the significance of the electromagnetic spectrum?

Back

The electromagnetic spectrum encompasses all types of electromagnetic radiation, including visible light, and illustrates the range of wavelengths and frequencies.

Front

What is a bright line spectrum?

Back

A bright line spectrum is a series of bright lines superimposed on a dark background, produced by the emission of light from excited atoms.
