### Question: An EM wave has a frequency of $2 \times 10^{14}$ Hz. What is the wavelength?### Options:- A. 1.5 nm- B. 1.5 km- C. 1.5 µm- D. 1.5 mm- E. 1.5 cm### Explanation:This question requires calculating the wavelength of an electromagnetic (EM) wave given its frequency. To solve, use the wave equation:\[ c = \lambda \times f \]where:- $ c $ is the speed of light ($3 \times 10^8$ m/s),- $ \lambda $ is the wavelength,- $ f $ is the frequency.### Step-by-Step Solution:1. Rearrange the equation to solve for wavelength:\[ \lambda = \frac{c}{f} \]2. Substitute the given values:\[ \lambda = \frac{3 \times 10^8 \text{ m/s}}{2 \times 10^{14} \text{ Hz}} \]3. Calculate the wavelength:\[ \lambda = 1.5 \times 10^{-6} \text{ m} \]4. Convert meters to micrometers ($1 \text{ m} = 10^6 \text{ µm}$):\[ \lambda = 1.5 \text{ µm} \]### Answer:The correct answer is C. 1.5 µm.
