A convex lens can focus light rays to a point, creating a hot spot. By adjusting the lens distance from the matchstick, you can focus the light to a small enough spot to heat the matchstick enough to ignite it.

When an object is is viewed through a convex lens held in front of a concave lens does the object get bigger or smaller?

When an object is viewed through a convex lens held in front of a concave lens, the object can appear either smaller or larger depending on the specific characteristics of the lenses and their relative positions. The combination of lenses can either magnify or reduce the size of the object.


Can you think of creating a shape that would give a circular shadow if held in one way and a rectangular shadow if held in another way?

Yes, a shape that could achieve this is a cylinder with a circular base. When held upright, it would cast a circular shadow, and when laid flat, it would cast a rectangular shadow due to the shape's profile and orientation relative to the light source.

What is the characteristics of Magnifying glass?

A magnifying glass is a convex lens that is used to magnify or enlarge the size of an object when held close to it. It works by bending light rays to focus them on the object, making it appear larger and easier to see details. Magnifying glasses are commonly used for tasks that require detailed inspection, such as reading small print or examining intricate objects.


Why is the leaf held at a right angle to the light source?

The leaf is held at a right angle to the light source to maximize the surface area exposed to sunlight for photosynthesis. This position ensures that the chloroplasts in the leaf receive optimal light energy for the process of photosynthesis to occur efficiently.

How can a convex lens light a match stick if held towards the sun?

The lens concentrates the sun's rays into a tiny point of heat, which causes a match or other combustible material to ignite.


How do magnifying glasses work?

A magnifying glass is much thicker than it is around the edges, which is called "convex". When this is held close to an object, the light waves are bent and this allows the object to appear larger than it is for better viewing.

How do you remove the rear interior light on a 2003 VW Jetta?

The light bulb housing is held in place by a metal clip that faces towards the front of the car (narrow side of housing). 1. Work a small slot screwdriver under the housing flashing and press the clip (trust that it is there--you can't see it). The housing will come out. 2. Unplug the housing from the wiring (which is held in by integrated plastic clips). 3. Remove the plastic cover on the back of the housing (it slides towards one of the long sides of the housing). The bulb is a C5W 12V. It is held in place by friction and can be popped out and a new one popped in easily. Plug the wiring back in and push the housing back into place when done. You may need to slide it forward (towards the front of the car) to make it stay in securely.
