Question

Method First step I performed was setting up the lab so I am comfortable and everything is in place. Then l placed a strip of the masking tape vertically on the opposite sides of the glass. I then measured the distance between the two strips of tape (0.09 m). The glass is empty first so I shined the laser through the glass at an angle with the horizontal. To make sure the laser stays at this point, I had my brother hold it in place (this worked really well!). I then positioned the laser, while my brother is holding it, so the laser beam is right beside both strips of the masking tape. What I did was write the entry and exit points on the masking tape For this, h, is known, of the two points. I then calculated the angle of incidence with the formula. ana, 1 = '11/11, in this case it was 0.09 m-1.1m. The next step I filled the glass with water in the same position. After filling the glass with water, I marked the entry and exit points again. I measured the height distance (h2) and calculated the refraction angle with tan,-"2/w which would be 0.09 m = 0.86 m

Explanation / Answer

Hi,

Please find the below solution.

Your unnderstanding is right.

but you need to take inverse for the value.

trail 1:-

1/0.6994

=1.429

trail 2:-

1/0.8341

=1.198

Trail 3:-

for this h2 vaue is 0.77

so value is 1/0.63

=1.58
