A student measures the critical angle of incidence for light passing from four different optical media, W, X, Y and Z, into air.
She takes 3 measurements of the critical angle (in degrees) for each medium.
| Medium | 1st measurement (∘^\circ∘) | 2nd measurement (∘^\circ∘) | 3rd measurement (∘^\circ∘) |
|---|---|---|---|
| W | 41.2 | 41.8 | 41.5 |
| X | 24.4 | 24.5 | 24.3 |
| Y | 35.6 | 35.1 | 35.9 |
| Z | 48.9 | 48.7 | 49.2 |
Which medium has the largest range of values?
Medium W
Medium X
Medium Y
Medium Z
