How do you convert kilohertz (kHz) to hertz (Hz)?

Back

To convert kilohertz to hertz, multiply by 1000. For example, 880 kHz = 880,000 Hz.

What is the wavelength of green light in meters if it is given as 565 nm?

Back

Front

How many photons of green light are needed to cause damage at 61 J if each photon has a wavelength of 565 nm?

Back

Approximately 1.74 x 10^20 photons are needed.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave, typically measured in meters.

Front

What is the definition of frequency?

Back

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

Front

How do you measure the wavelength of a sound wave?

Back

Wavelength can be measured from compression to compression or from trough to trough.
