What is the frequency of a photon of blue light, if it has a wavelength of 440 nm?
L= V / F.
300m/uS / F = 440*10^-9 m.
440*10^-9F = 300.
F = 300 / 440*10^-9 = 0.6818*10^9 =
6.818*10^8 Mhz
To calculate the frequency of a photon, you can use the following equation:
Speed of light (c) = Wavelength (λ) × Frequency (f)
The speed of light is approximately 3.00 × 10^8 meters per second (m/s). However, we need the wavelength in meters, so we convert it.
Given:
Wavelength (λ) = 440 nm
To convert nanometers (nm) to meters (m), we divide by 10^9:
Wavelength (λ) = 440 nm ÷ 10^9 = 4.40 × 10^-7 meters (m)
Now, we can rearrange the equation to solve for frequency (f):
Frequency (f) = Speed of light (c) ÷ Wavelength (λ)
Plugging in the values:
Frequency (f) = (3.00 × 10^8 m/s) ÷ (4.40 × 10^-7 m)
Frequency (f) ≈ 6.82 × 10^14 Hz
Therefore, the frequency of a photon of blue light with a wavelength of 440 nm is approximately 6.82 × 10^14 Hz.
To find the frequency of a photon, you can use the formula:
Frequency = speed of light / wavelength
The speed of light, denoted by the symbol 'c', is a constant value of approximately 3 x 10^8 meters per second.
Given the wavelength of blue light as 440 nm (nanometers), we need to convert it to meters by dividing it by 10^9 (since there are 1 billion nanometers in a meter):
Wavelength in meters = 440 nm / 10^9 = 440 x 10^-9 meters
Now you can plug the values into the formula to find the frequency:
Frequency = (3 x 10^8 m/s) / (440 x 10^-9 m)
Calculating this expression gives us:
Frequency ≈ 6.81 x 10^14 Hz
Therefore, the frequency of a photon of blue light with a wavelength of 440 nm is approximately 6.81 x 10^14 Hz.
