    They are the same thing, the point where the rays converge or appear to converge. FYI....The focal length is the distance from the focal point to the lens or mirror.

    If you move the object closer to the concave lens does the virtual image become bigger or smaller (than the former one)?

    • @stepbystepscience
      @stepbystepscience  9 років тому

      +pink cookie princess Yes, as the object gets closer to the lens the image gets bigger. When the object is at the lens then image and the object are the same size are the same size.

    • @stepbystepscience
      @stepbystepscience  9 років тому +1

      +Peter Pachis Great question, You only need to draw two lines, the image will appear where they intersect. You can always draw more, a third, to confirm that you drew the first two correctly. Sometimes it is a little harder to draw the third if your overall sketch is not to scale.

      @@stepbystepscience thank you sir, i understand with your explanation. Yesterday, when I still learn about lens, I saw another video said, the object can put in front of the lens or what i mean in the virtual condition. Before that, I never heard that condition.

      And until now, he didn't answered my question, "Why you can put images in front of the lens or in the virtual condition? And I asked her explanation what the application in the daily life when he put object in the virtual condition at concave lens?"

    What if my mirror is not big enough, can i draw 2 lines connected to focal point and Centre of curvature without touching the mirror?

    • @stepbystepscience
      @stepbystepscience  9 років тому

      Lee Yong Ee I am sorry I don't quite understand your question but for lenses you can just extend the center line of the lens and use that line for your refraction. In this case if the lens is too small or the object is too big you can use the line to locate the image. You can use the same concept for the mirrors as long as you follow the ray drawing rules. Sorry I know that is a bit vague.

      Brian Swarthout Sorry I forgot to mention I was asking about the convex mirror. What if I apply it in a real case which I know the actual dimension of mirror and I need to find out the maximum area that the mirror can cover? How should I determine where is the limit of coverage?
