Question

Calculate the frequency of light that has a wavelength of 4.25 x 10⁻⁹m.

a. 4.16 * 10⁴⁸
b. 1.56* 10⁻⁵⁶
C. 7.06* 10¹⁶
d. 7.06* 10⁻²

Answer 1

The frequency of light with a wavelength of 4.25 x 10⁻⁹ m is calculated using the speed of light and the wavelength. The correct frequency is 7.06 x 10⁹⁶ Hz, answer choice (c).

Step-by-step explanation:

To calculate the frequency of light given the wavelength, you can use the formula:

c = λ * ν

where c is the speed of light in a vacuum (approximately 3.00 × 10⁸ m/s), λ (lambda) is the wavelength, and ν (nu) is the frequency of the light. To find the frequency, rearrange this formula to solve for ν:

ν = c / λ

For a wavelength of 4.25 x 10⁻⁹ m, we can then calculate:

ν = (3.00 × 10⁸ m/s) / (4.25 x 10⁻⁹ m)

ν = 7.06 × 10¹⁶ Hz

So, the correct answer is c. 7.06× 10¹⁶.

The subject of this question falls under Physics which often involves concepts such as the electromagnetic spectrum, wavelengths, and frequencies.
