Question

1.

(a) The speed of a 500 nm light is 3 .00x10^8 m/s in vacuum and 1.95x10^8 m/s in a certain glass. What is the
index of refraction of the light?

(b) What is the frequency of the 500 nm light in a vacuum?

(c) What is the frequency of the 500 nm light in the glass?

(d)If the 500 nm light is incident on a flat boundary between the glass part in Ia and air (nair= 1.00) as
shown, what is the angle of reflection? Sketch on the given diagram. Do the same
work for the refracted ray.

The image depicts a diagram of light refraction and reflection at the boundary between glass and air.

**Diagram Details:**

1. **Mediums:**
   - The left side is labeled as "Glass."
   - The right side is labeled as "Air."

2. **Incident Ray:**
   - A ray is shown hitting the boundary at an angle.
   - The angle of incidence is marked as \(30^\circ\) from the normal (a dashed vertical line perpendicular to the boundary).

3. **Refracted Ray:**
   - The refracted ray is shown bending away from the normal as it enters the air, labeled "refracted."

4. **Reflected Ray:**
   - The reflected ray is shown bouncing off the boundary and is labeled "reflected."

5. **Error Note:**
   - A handwritten note states, "This sketch is wrong."

**Additional Points:**

- The normal line is the dashed line at the boundary, perpendicular to the surface separating the two mediums.
- The angles are measured from the normal line, not the boundary surface itself. Therefore, the specific critique of the sketch may pertain to inaccuracies in the angles depicted for refraction or reflection based on Snell's Law, which governs these measurements.

This diagram attempts to illustrate the basic principles of refraction and reflection occurring as light transitions between different mediums, although the sketch has been noted as incorrect, pointing to potential additional explanations needed regarding accurate angles or depiction.
