Section B: Calculation Problems (Aktiviti 13.2)

Question 1:
The speed of light in a medium is 2.0 × 10⁸ m/s. Calculate the refractive index of the medium. (Speed of light in vacuum = 3.0 × 10⁸ m/s)

Jawapan:
n = speed of light in vacuum / speed of light in medium
n = (3.0 × 10⁸) / (2.0 × 10⁸) = 1.5

Question 2:
A light ray travels from water (n = 1.33) into air. The angle of incidence in water is 35°. Calculate the angle of refraction in air.

Jawapan:
Using Snell’s Law: n₁ sin i = n₂ sin r
1.33 × sin 35° = 1.00 × sin r
1.33 × 0.574 = sin r
sin r = 0.763
r = sin⁻¹ (0.763) = 49.8°

Understanding Aktiviti 13: Topic Overview

Before diving into the answers, let’s confirm the topic. In most KSSM Physics Form 4 textbooks, Aktiviti 13.1 to 13.5 covers:

  • 13.1 – Refraction of Light
  • 13.2 – Snell’s Law & Refractive Index
  • 13.3 – Total Internal Reflection & Critical Angle
  • 13.4 – Lenses (Convex & Concave)
  • 13.5 – Optical Instruments (Telescope, Microscope, Periscope)

If your Aktiviti 13 focuses on Total Internal Reflection (a popular exam topic), you are in the right place. Section B: Calculation Problems (Aktiviti 13

Section E: Optical Instruments (Aktiviti 13.5 – Periscope)

Question:
Draw a labelled diagram of a periscope using two prisms. Explain how total internal reflection helps in image formation.

Jawapan:

  • The periscope uses two right-angled prisms.
  • Light from the object enters the top prism, undergoes total internal reflection (45° incidence > critical angle for glass ≈ 42°), and is directed down the tube.
  • The second prism again reflects the light by 90° into the eye.
  • Advantage over mirrors: Prisms reflect 100% of light (no loss), giving a brighter image.

Introduction

The Fizik Tingkatan 4 KSSM textbook is an essential resource for students in Malaysia. One of the most challenging sections is Aktiviti 13, which typically falls under the final chapters involving light, optics, or wave mechanics. Many students search for "jawapan buku teks fizik tingkatan 4 kssm aktiviti 13 top full" to verify their answers and understand the reasoning behind each solution. This article provides a complete, step-by-step answer guide for Aktiviti 13, ensuring you grasp the underlying physics concepts, not just the final answers.

Note: Aktiviti numbers may vary slightly across textbook editions. Aktiviti 13 commonly refers to experiments or problem-solving tasks related to Refraction of Light, Lenses, or Total Internal Reflection. The answers below are based on the standard KSSM Physics Form 4 textbook (2020-2025 syllabus).

4. Menghasilkan Graf

  • Graf Jarak (s) vs Masa (t): titik data (t, s) gunakan masa purata pada setiap jarak.
    • Jika graf hampir lurus, gerakan berterusan dengan halaju hampir malar.
    • Kecerunan (slope) graf s–t = halaju purata.
  • Graf Halaju (v) vs Masa (t): gunakan nilai halaju purata bagi setiap selang, plot pada jejari masa yang sesuai (contoh, nilai halaju antara 0–0.5 m diplot pada t ≈ 0.23 s).
    • Kecerunan graf v–t = pecutan.

Contoh kiraan kecerunan (s–t) 0 → 2.0 m:

  • slope = Δs / Δt = 2.0 / 2.033 ≈ 0.984 m/s (lihat sama seperti halaju purata).
