Experiment 8: Mirrors

Purpose: To explore the images formed by convex and concave mirrors through direct observations and light ray diagrams

Equipment:

• Convex mirror
• Concave mirror
• Worksheets at the end of lab activity packet
• Ruler
• Object(myself)



Experiment:

Part A - Convex Mirror


Far Away from Convex Mirror

From the direct observations, a convex mirror will make an object appear smaller than the same size object from a far distance. This object remains upright.




Clore up to Convex Mirror



As the object is brought close up to the convex mirror, the image appears larger than the same size real object.


From a farther distance than the first picture, the image appears to be so far it disappears.

Part B - Concave Mirrors

Close up to Concave Mirror

As the object(me) got closer to the mirror, the image became bigger and remained upright.





Close up to Concave Mirror

As the object was much further away, the mirror image was much smaller and inverted, as depicted in the picture above.

Conclusion:

Based on the light ray sketches, bellow of a convex and concave mirror respectively, we can conclude that the observations and calculations match based on the magnification value.
