FLASHCARD QUESTION

Front

What is the formula to calculate the energy of a photon based on its frequency?

Back

E = h * f, where E is energy, h is Planck's constant (6.626 x 10^-34 J·s), and f is frequency.

2.

FLASHCARD QUESTION

Front

How do you convert wavelength from nanometers to meters?

Back

To convert from nanometers to meters, divide the value in nanometers by 1,000,000,000 (or multiply by 10^-9).

3.

FLASHCARD QUESTION

Front

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

Back

The relationship is given by the equation c = λ * f, where c is the speed of light (approximately 3.00 x 10^8 m/s), λ is wavelength, and f is frequency.

4.

FLASHCARD QUESTION

Front

What happens to the energy of photons as the frequency increases?

Back

As the frequency increases, the energy of the photons also increases.

5.

FLASHCARD QUESTION

Front

What is the energy of a photon with a frequency of 4.5 x 10^18 Hz?

Back

The energy is approximately 2.98 x 10^-15 joules.

6.

FLASHCARD QUESTION

Front

What is the frequency of light emitted by an argon ion laser at a wavelength of 488 nm?

Back

The frequency is approximately 6.14 x 10^14 Hz.

7.

FLASHCARD QUESTION

Front

How does the energy of shorter waves compare to that of longer waves?

Back

Shorter waves have higher energy, while longer waves have lower energy.
