Data:θ = 60°Table 3: Number of images appear and the distance the images is from the vertex.Number of imagesDistance from object to vertex of mirror117.7cm311.4cm59cmConclusion:At the end of this part of this experiment we concluded that when moving the pin closertowards the vertex we see more and more images. The reason for that is that since the image isgoing inside the vertex more light is reflected off the pin which makes it appear multiple times.Also after looking at the diagram, I think that the diagram was consistent since you can tell thatthe further the pin is from the vertex the images seen gets lower and lower. Also we have toconsider the person viewing the pin, If they look at the pin at a certain angle some pins will notappear.
Part 4: RefractionProcedure:Get another sheet of paper and lay the glass plate in the center. Place an object pin “A”next to the glass about 1 cm from the corner. Place a second pin “B” on the opposite side of theplate about 1 cm from the diagonal corner. Mark these two positions. Place a third pin “A’”
which marks the apparent image of the object point A. Remove the pins and the glass and drawin the normal to the glass plate at the position of the object pin A. Measure the angles. Repeat theabove procedure so that the incident angles change.Data:Table 4:Incident rays for part 4 of the experiment.IncidentΘiΘinIncident ray 139.526.51.425Incident ray 249321.424Incident ray 327171.553Average value of n = 1.4387Calculation by Hand:nair1=()nairsinθinglasssin θr. =(. )sin39 5nglasssin 26 5=nglass.1 425Conclusion:At the end of this part of the experiment we notice that the light does bend when it goesthrough a glass plate. This means that the velocity of the waves changes causing deflection.Lab 4: Conclusion/ QuestionsQuestions:
