**Text Transcription and Explanation for Educational Website** --- ### Understanding Refraction and Reflection Consider a ray of light in a medium with an index of refraction \( n_1 \). It is incident on an interface with another medium that has an index of refraction \( n_2 \). The angle of incidence is \( \theta_1 \), the angle of reflection is \( \theta' \), and the angle of refraction is \( \theta_2 \). #### Questions: 1. **Index of Refraction Comparison:** What must be true about \( n_1 \) compared to \( n_2 \)? - (A) \( n_1 < n_2 \) - (B) \( n_1 = n_2 \) - (C) \( n_1 > n_2 \) 2. **Wavelength Comparison:** What must be true about the wavelength of the light in the first medium (\( \lambda_1 \)) compared to the wavelength of the light in the second medium (\( \lambda_2 \))? - (A) \( \lambda_1 < \lambda_2 \) - (B) \( \lambda_1 = \lambda_2 \) - (C) \( \lambda_1 > \lambda_2 \) 3. **Speed of Light Comparison:** What must be true about the speed of the light in the first medium (\( v_1 \)) compared to the speed of the light in the second medium (\( v_2 \))? - (A) \( v_1 < v_2 \) - (B) \( v_1 = v_2 \) - (C) \( v_1 > v_2 \) --- #### Reflection and Refraction Scenarios: 1. **If light in medium 1 is incident on medium 2 at 35° relative to the normal line, would any of it refract?** - (A) All of it - (B) None of it - (C) Some of it 2. **If light in medium 1 is incident on medium 2 at 25° relative to the normal line, would any of it refract?** - (A) All of it - (B) None of it - (C) Some of
