Wave Relationships: Frequency, Wavelength, and Energy

Vocabulary flashcards covering the relationships between energy, frequency, wavelength, units, and constants discussed in the lecture.

Nu ($\nu$)

The variable representing frequency (also referred to by the speaker as "v" or "new"), measured in inverse seconds ($\text{s}^{-1}$) and directly proportional to energy.

Lambda ($\lambda$)

The variable representing wavelength, which can be found by first calculating nu ($\nu$) or by rearranging the energy equation directly, with final values expressed in meters or nanometers.

Inverse seconds ($\text{s}^{-1}$)

The unit of frequency (given in the example as $6.88 \times 10^{14}\,\text{s}^{-1}$) that cancels out in division to yield wavelength in meters.

Direct relationship between frequency and energy

The physical principle stating that the higher the frequency of a wave, the higher its energy.

Inverse relationship between wavelength and energy

The physical principle stating that a longer wavelength corresponds to lower energy because the frequency is also lower.

Flank's constant

The constant named in the lecture (also referred to in Chapter 2 as "plant's aspect") that is multiplied by frequency ($\nu$) in the energy relationship.

Nanometer ($\text{nm}$)

The required unit of measurement for the final wavelength ($\lambda$) answer after converting and canceling joules.
