Upside down!

            We walked into the classroom today and there was a HUGE mirror in the classroom but the thing is the mirror was an inverted mirror. So the ground looked like the ceiling and everything was turned upside down!

            Again we worked with lasers and mirrors today but we learned many things too! Including the characteristics of images! They were real vs. virtual, upright vs. inverted, and magnified vs. reduced! Real meant that the light converges at one point and virtual is when the light doesn’t converge at the image it almost looks like the light is going through the mirror to the image. Upright is when the image appears right side up and inverted just means that the image is upside down! Magnified is when the object or image appears bigger than it really is and reduced is the opposite is when the image appears smaller than normal.

            We then began learning about refraction. Refraction is the changing of direction of a wave due to changes in wave speed due to medium. We learned that along with refraction came the index of refraction. The equation was N (index of refraction)= speed of light in a vacuum (3 X10⁸) / speed of light in a medium! We also learned that if two objects have the same index of refraction that they disappear. Refraction allows you to hide or view different objects. We learned that the larger the index of refraction , the slower the speed of light in that medium! We also learned that If a light is going from a faster to a slower index that the way the light bends will be towards the normal, but if the light is going from a slower to a faster index then the light will bend away from the normal.

            Finally we ended the day by learning about converging lenses, when it makes light converge, and diverging lenses, when the lenses makes light spread out.

            This is a picture of my friends and I that we took in the inverted mirror. We flipped it right side up though so that we could see what it looks like. The actual picture is actually upside because the mirror is inverted.
