See how the shape of the eyeball affects where light focuses inside the eye.
Adjust the eyeball length and apply lenses to understand why vision becomes blurry and how glasses correct it.
Clear vision occurs when light focuses exactly on the retina.
Quick Guide
1) Change Eyeball Length
Too long → Focus forms before the retina → Myopia (Nearsightedness)
Too short → Focus forms behind the retina → Hypermetropia (Farsightedness)
2) Observe the Focus Point
Watch the yellow point where light rays meet.
On the retina → Clear vision
Before or behind the retina → Blurred vision
3) Apply a Lens
Concave lens → Moves focus backward (corrects myopia)
Convex lens → Moves focus forward (corrects hypermetropia)
Challenge
Change the eyeball length to create blurred vision.
Now adjust the lens strength to bring the focus back exactly onto the retina.
See electric and gravitational forces in action. Place positive (red) and negative (blue) particles and watch how they move. Like charges repel, unlike charges attract, and gravity always pulls particles together. Toggle gravity to compare effects.
Quick Guide:
1) Electric Force (Gravity OFF)
Red + Red → repel
Red + Blue → attract
Closer particles → stronger force
2) With Gravity (ON)
Gravity pulls all particles
Repulsion reduces slightly
Attraction becomes stronger
3) Challenge
Place 3 particles so one stays completely still (zero net force).
Click on the canvas to place particles. Drag them to see the forces!
**Concept Check:** Notice how all particles move toward each other slightly when Gravitational Force is ON (always attractive, due to mass), but the Electric Force (attraction/repulsion, due to charge) is much stronger and dominates the movement.
