The correct Answer is:
To determine the frequency of light after reflection, we can follow these steps: ### Step 1: Understand the properties of light during reflection When light reflects off a surface, certain properties of the light wave remain unchanged. These properties include the speed of light in the medium, the frequency of the light, and the wavelength of the light. ### Step 2: Identify the frequency of the incident light The problem states that the frequency of the incident light is \(3 \times 10^{18}\) Hz. ### Step 3: Analyze the effect of reflection on frequency Since reflection does not change the frequency of light, we can conclude that the frequency after reflection will be the same as the frequency before reflection. ### Step 4: State the frequency after reflection Thus, the frequency of the light after reflection will also be \(3 \times 10^{18}\) Hz. ### Conclusion The frequency of the incident light remains unchanged after reflection. Therefore, the frequency after reflection is \(3 \times 10^{18}\) Hz. ---
