⚡ FORCE ON A CURRENT-CARRYING CONDUCTOR — QUICK NOTES 🔹 Magnetic Force on a Current-Carrying Conductor A current-carrying conductor placed in a magnetic field experiences a force. Formula: F = BIL sinθ where, F = Magnetic Force B = Magnetic Field I = Current L = Length of the Conductor θ = Angle between the conductor and the magnetic field 🔹 Special Cases • θ = 0° or 180° F = 0 (Conductor parallel to the magnetic field) • θ = 90° F = BIL (Maximum Force) 🔹 Direction of Force Determined by Fleming's Left-Hand Rule First Finger → Magnetic Field (B) Second Finger → Current (I) Thumb → Force (F) 🔹 Force Between Two Parallel Current-Carrying Conductors F/L = μ₀I₁I₂/2πd where, I₁, I₂ = Currents in the Conductors d = Distance Between the Conductors 🔹 Torque on a Current Loop τ = NIAB sinθ where, N = Number of Turns A = Area of the Loop 🔹 Magnetic Dipole Moment M = NIA 🔹 Torque on a Magnetic Dipole τ = MB sinθ ⚡ OLYMPIAD FACTS ✓ A conductor experiences maximum force when it is perpendicular to the magnetic field. ✓ No force acts when the conductor is parallel to the magnetic field. ✓ Parallel currents in the same direction attract each other. ✓ Parallel currents in opposite directions repel each other. ✓ The SI unit of magnetic field is tesla (T). 🎯 MUST REMEMBER F = BIL sinθ F_max = BIL F/L = μ₀I₁I₂/2πd τ = NIAB sinθ M = NIA τ = MB sinθ

🌈 REFRACTION & TOTAL INTERNAL REFLECTION — FORMULA SHEET 🔹 Refractive Index n = c/v where, n = Refractive Index c = Speed of Light in Vacuum v = Speed of Light in the Medium 🔹 Relative Refractive Index n₂₁ = n₂/n₁ = v₁/v₂ 🔹 Snell's Law n₁ sin i = n₂ sin r 🔹 Critical Angle sin C = n₂/n₁ (for n₁ > n₂) 🔹 Condition for Total Internal Reflection (TIR) 1. Light must travel from a denser medium to a rarer medium. 2. Angle of incidence must be greater than the critical angle. 🔹 Apparent Depth Apparent Depth = Real Depth/n 🔹 Real Depth Real Depth = n × Apparent Depth 🔹 Lateral Shift (Parallel Slab) d = t × sin(i − r)/cos r where, t = Thickness of Slab 🔹 Optical Path Length OPL = nd 🔹 Speed of Light in a Medium v = c/n ⚡ OLYMPIAD FACTS ✓ The frequency of light remains unchanged during refraction. ✓ The wavelength changes when light enters a different medium. ✓ Total Internal Reflection occurs only when light travels from a denser medium to a rarer medium. ✓ A diamond sparkles due to repeated Total Internal Reflection. ✓ Optical fibres work on the principle of Total Internal Reflection. 🎯 MUST REMEMBER • n = c/v • n₂₁ = n₂/n₁ = v₁/v₂ • n₁ sin i = n₂ sin r • sin C = n₂/n₁ • Apparent Depth = Real Depth/n • Real Depth = n × Apparent Depth • d = t × sin(i − r)/cos r • OPL = nd • v = c/n .

The adjacent figure shows positions of an object O and its image I formed by a mirror. This is possible if:
1 231

MIRRORS & LENSES — FORMULA SHEET 🔹 Mirror Formula 1/f = 1/v + 1/u where, f = Focal Length u = Object Distance v = Image Distance 🔹 Magnification (Mirror) m = hᵢ/hₒ = −v/u 🔹 Radius of Curvature R = 2f 🔹 Lens Formula 1/f = 1/v − 1/u 🔹 Magnification (Lens) m = hᵢ/hₒ = v/u 🔹 Power of a Lens P = 1/f Unit = Dioptre (D) 🔹 Combination of Thin Lenses (In Contact) P_eq = P₁ + P₂ + P₃ + ... 🔹 Equivalent Focal Length 1/F = 1/f₁ + 1/f₂ + ... 🔹 Lens Maker's Formula 1/f = (n − 1)(1/R₁ − 1/R₂) 🔹 Linear Magnification m = Image Height/Object Height 🔹 Transverse Magnification m = Image Size/Object Size ⚡ OLYMPIAD FACTS ✓ Convex mirror always forms a virtual, erect, and diminished image. ✓ Concave mirror can form real or virtual images depending on the object position. ✓ Convex lens forms a real image when the object is beyond the focal point. ✓ Concave lens always forms a virtual, erect, and diminished image. ✓ A ray passing through the optical centre of a thin lens emerges undeviated. 🎯 MUST REMEMBER • Mirror Formula: 1/f = 1/v + 1/u • Lens Formula: 1/f = 1/v − 1/u • Mirror Magnification: m = −v/u • Lens Magnification: m = v/u • Radius of Curvature: R = 2f • Power of Lens: P = 1/f • Lens Maker's Formula: 1/f = (n − 1)(1/R₁ − 1/R₂)

A person with long-sightedness (hypermetropia) cannot see objects clearly at distances less than 100 cm. The power of the lens required to read an object placed at the normal near point (25 cm) is:
