Question

infrared radiation falls in the wavelength region of 1.00×10-6 to 1.00×10-3 meters. what is the frequency of infrared radiation that has a wavelength of 9.40×10-5 m?

Answer 1

The frequency of infrared radiation with a wavelength of 9.40×10-5 meters is approximately 3.19×10^12 Hz.

Step-by-step explanation:

Infrared radiation falls in the wavelength region of 1.00×10-6 to 1.00×10-3 meters. To calculate the frequency of infrared radiation with a wavelength of 9.40×10-5 meters, we can use the formula:

frequency = speed of light/wavelength

Where the speed of light is approximately 3.00×108 meters per second. Plugging in the given values:

frequency = (3.00×108 m/s) / (9.40×10-5 m) = 3.19×1012 Hz

Answer 2

The frequency of an infrared wave with a wavelength of 9.40× 10-5 m is approximately 3.19 × 1012 Hz, calculated using the formula c = λf with the speed of light and the given wavelength.

Step-by-step explanation:

The frequency of an electromagnetic wave, such as infrared radiation, can be determined by using the formula c = λf, where c is the speed of light in a vacuum (approximately 3.00 × 108 m/s), λ is the wavelength, and f is the frequency.

For infrared radiation with a wavelength of 9.40×10-5 m, we can rearrange the formula to find the frequency: f = c / λ.

Substituting the given values, the calculation is f = (3.00× 108 m/s) / (9.40× 10-5 m). The resulting frequency is approximately 3.19 × 1012 Hz.
