What was the first camera like? The camera is a great invention. It allows us to do anything from taking pictures of our loved ones and capturing memories to making fine art. But this makes me think‚ what was the first camera like? Before there where cameras like the ones we use today‚ photos were taken using the camera obscura. They were dark chambers with a small lens or pinhole (so it was also called a pin-hole camera). The light that came through the pinhole was then projected onto

I even took pictures of the sunset and it was beautiful. I wanted to take more pictures but I ran out of film. I asked my dad for more film but he never brought me more.

4. Some of the camera angles in the film are different from most movies. The camera angles depicting Truman give kind of a stalker vibe‚ because they are not normal cameras‚ and he is obviously not aware they are there. Three strange camera angles we see are behind Truman’s mirror‚ on the neighbors trash can‚ and in the radio of Truman’s car. These are not camera angles you see in most movies‚ because in most movies‚ the actors are aware they are being filmed‚ so cameras do not need to be hidden

Dispersion and the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming

Sadie Broadway Speed of Sound In Air We are studying the speed of sound in air currently in our physics class. The speed of sound is the distance traveled by a sound wave through an elastic medium during a period of time. The speed of sound is extremely interesting‚ as it’s actually the speed of transmission of a small disturbance through a medium. The speed of sound occurs constantly‚ whenever a sound is heard. It’s everywhere‚ and in air we are discovering certain factors like altitude and air

Clocking the Speed of Light Why is the speed of light important? -Having a accurate number for the speed of light allows for accurate measurements of the universe around us -Even small inaccuracies make large differences when measuring the space between stars‚ planets‚ and galaxies -The more precise our measurement of the speed of light the more precise our measurements are of the universe because light is the universal measurement used Light as Infinite -Most scholars agreed that light
