light is an electromagnetic wave and travels at a speed of 3.00 x 108 m/s. the human eye is most sensitive to yellow-green light which has a wavelength of 5.45 x 10-7 m. what is the frequency of this light?
5.5x10^14 hertz
56
To calculate the frequency of light, we can use the formula:
speed of light = wavelength x frequency
Given the speed of light as 3.00 x 10^8 m/s and the wavelength of yellow-green light as 5.45 x 10^-7 m, we can substitute these values into the formula:
3.00 x 10^8 m/s = 5.45 x 10^-7 m x frequency
To solve for the frequency, we can rearrange the equation:
frequency = (3.00 x 10^8 m/s) / (5.45 x 10^-7 m)
Now, we can plug in the values and calculate the frequency:
frequency ≈ 5.50 x 10^14 Hz
Therefore, the frequency of yellow-green light is approximately 5.50 x 10^14 Hz.
To find the frequency of light, we can use the formula:
Speed of light = Wavelength x Frequency
Given:
Speed of light (c) = 3.00 x 10^8 m/s
Wavelength (λ) = 5.45 x 10^(-7) m
We need to rearrange the formula to solve for frequency (f):
Frequency = Speed of light / Wavelength
Now let's substitute the given values into the formula:
Frequency = (3.00 x 10^8 m/s) / (5.45 x 10^(-7) m)
To divide the numbers, we need to subtract the exponents:
Frequency = (3.00 x 10^8) / (5.45 x 10^(-7)) = 5.50 x 10^14 Hz
Therefore, the frequency of yellow-green light is approximately 5.50 x 10^14 Hz.
