у=35°

Answer 2

Finding the Angle of Refraction

To find the angle of refraction when light passes from water to glass with an incident angle of 45°, we can use Snell's Law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the velocities of light in the two media.

According to Snell's Law: \[ \frac{\sin(\theta_1)}{\sin(\theta_2)} = \frac{v_1}{v_2} \]

Where: - \( \theta_1 \) = angle of incidence - \( \theta_2 \) = angle of refraction - \( v_1 \) = velocity of light in the first medium - \( v_2 \) = velocity of light in the second medium

Calculation

Given: - Angle of incidence, \( \theta_1 = 45° \)

We need to find the angle of refraction, \( \theta_2 \).

From the search results, we can calculate the angle of refraction using the formula: \[ \frac{\sin(45°)}{\sin(\theta_2)} = \frac{v_{\text{water}}}{v_{\text{glass}}} \]

Unfortunately, the specific velocities of light in water and glass are not provided in the search results. Therefore, it's not possible to calculate the exact angle of refraction without this information.

If you have the specific refractive indices of water and glass, we can use them to calculate the angle of refraction using the formula: \[ \frac{\sin(45°)}{\sin(\theta_2)} = \frac{n_{\text{glass}}}{n_{\text{water}}} \]

Please provide the refractive indices of water and glass if available, so we can proceed with the calculation.
