🔍 What You'll Get:

Kya aapne kabhi dekha hai ki jab hum kisi paani bhare tub ya talab mein dekhen, to koi object (jaise sikka) actual jagah se zyada upar dikhai deta hai? Aakhir yeh kaise hota hai?

Yeh hota hai ek optical illusion ke kaaran – jise hum kehte hain:

Real Depth aur Apparent Depth ka Fark! 🔍
---

1. Real Depth (Vastavik Gehrai) 📏
Yeh woh actual distance hai jo object surface ke neeche hota hai.
Example: Agar ek sikka paani mein 10 cm neeche hai, to uski real depth = 10 cm.
---

2. Apparent Depth (Pratit Gehrai) 👁️
Yeh woh gehrai hoti hai jitni gehrai tak object humein dikhai deta hai – jo hamesha real depth se kam hoti hai.
Example: Upar wale example mein woh sikka shayad sirf 7 cm gehra dikhega.

3. Yeh Illusion Kyon Hota Hai? 🤔💡
Jab light kisi denser medium (jaise paani) se rarer medium (jaise hawa) mein aati hai, to woh refraction karti hai – yaani light ki direction thodi badal jaati hai.
Hamari aankh is light ko seedha samajh kar object ko usse upar kahin dekh leti hai – isi liye object chhota ya upar dikhai deta hai.
---

4. Refraction – Bending of Light 🌈🔬
Refraction is the key reason behind this phenomenon.
Jab light ray paani se nikalti hai aur hawa mein jaati hai, to woh away from normal bend karti hai – aur humein object apni original jagah se upar dikhai deta hai.

5. Formula (Physics ke students ke liye) 📚
Apparent Depth = Real Depth × (Refractive Index of Medium 2 / Medium 1)
For water to air:
Apparent Depth = Real Depth ÷ Refractive Index of Water (≈ 1.33)

6. Kahaan Dekhne Ko Milta Hai? 🔭

Talab ya swimming pool mein chhoti cheezein upar dikhai dena

Glass mein rakha spoon tedha ya chhota dikhai dena

Scuba diving ke samay cheezein paas lagna

Aquarium mein fish zyada badi ya chhoti dikhna
---

7. Fun Fact! 🧠
Fishermen ya divers ko yeh concept dhyaan mein rakhna padta hai – kyunki jo machhli unhe 1 meter door dikhti hai, woh asal mein usse zyada door hoti hai!
---

Conclusion:
Real aur Apparent Depth ke beech ka fark ek simple optical illusion hai – lekin yeh batata hai ki humari aankhon par humesha bharosa nahi kiya ja sakta – kabhi-kabhi science ko bhi samajhna padta hai! 👁️➡️🔬
