Thin Lens Equation Calculator Example

Given Values

Focal Length (f): 0.10 m
Object Distance (do): 0.25 m
Object Height: 0.02 m

Step-by-Step Solution

1/f = 1/do + 1/di

1/di = 1/f − 1/do

1/di = 1/0.10 − 1/0.25

di = 0.1667 m

M = −di / do = −0.6667

Result

Image Distance: 0.1667 m
Magnification: −0.6667
Image Type: Real
Orientation: Inverted
Size: Reduced

This feature makes All Calculator’s thin lens equation calculator perfect for quick and reliable results.

Mirror Equation Calculator Example

A concave mirror has:
Focal Length: 0.20 m
Object Distance: 0.60 m
Object Height: 0.03 m

Using the mirror equation calculator, image distance, magnification, and image nature are calculated instantly.
If results do not appear, ensure all values are entered correctly and units are consistent.

Snell’s Law Calculator Example

Light passes from air into glass at a 30° incident angle.

Given Values

Refractive Index (n₁): 1.00 (air)
Refractive Index (n₂): 1.50 (glass)
Incident Angle (θ₁): 30°

Step-by-Step Solution

n₁ sin(θ₁) = n₂ sin(θ₂)

θ₂ = arcsin[(n₁/n₂) sin(θ₁)]

θ₂ = 19.47°

Final Result

Refracted Angle: 19.47°
Total Internal Reflection: No
