Given the following information:
Planck's constant = 6.626x10^-34 J s
1 nm = 10^-9m
Speed of light = 3x10⁸m/s
100 cm per meter
Calculate the wavelength (cm) of energy in the IR range with a frequency 8.4x10¹²s^-1

Question

Quizplus · Accepted Answer

The correct answer is A.The wavelength of energy is given by the equation:$$\lambda = \frac{c}{f}$$where:* $\lambda$ is the wavelength in meters* $c$ is the speed of light in meters per second* $f$ is the frequency in hertzSubstituting the given values into the equation, we get:$$\lambda = \frac{3x10^8 m/s}{8.4x10^{12} s^{-1}} = 3.6x10^{-3} m$$Converting meters to centimeters, we get:$$\lambda = 3.6x10^{-3} m 	imes \frac{100 cm}{1 m} = 3.6x10^{-3} cm$$
