Final answer:
The frequency of light with a wavelength of 2.50 x 10⁻⁷m is approximately 1.2 x 10¹⁵ Hz.
Step-by-step explanation:
The frequency of light can be calculated using the equation:
frequency = speed of light / wavelength
Given that the wavelength is 2.50 x 10⁻⁷m, and the speed of light is approximately 3.00 x 10⁸ m/s, we can substitute these values into the equation:
frequency = (3.00 x 10⁸ m/s) / (2.50 x 10⁻⁷m)
Performing the calculation, the frequency of light is approximately 1.2 x 10¹⁵ Hz.
