Understand what a pinhole camera is and its purpose in optics.
Learn the principle of rectilinear propagation of light.
Observe how images are formed without a lens.
Develop hands-on skills by constructing a working DIY camera.
Connect the experiment to real-world camera technology and photography concepts.
A pinhole camera creates an inverted image of objects on a screen or film.
Light travels in straight lines, which is why a small pinhole can project an image.
The size of the pinhole affects the clarity and brightness of the image.
Building a DIY pinhole camera reinforces concepts of optics in a tangible way.
This simple experiment demonstrates the fundamentals of photography and image formation.
