The West African Examinations Council (WAEC) conducts the GCE (General Certificate Examination) annually, and the Physics Practical exam is a crucial component. This examination evaluates candidates on their ability to apply practical physics knowledge to real-life situations. To excel in this test, you need to be well-versed in various practical experiments and their corresponding questions and answers.

WAEC GCE 2023/2024 Physics Practical Expo - 2nd Series

Experiment 1: Determination of Acceleration Due to Gravity (g)

Question:

1. Explain the procedure for determining 'g' using a simple pendulum.

Answer: To determine 'g' using a simple pendulum, follow these steps:

• Attach a small mass to a string and suspend it from a fixed point.
• Displace the mass slightly from its equilibrium position and release it.
• Measure the time taken for the pendulum to complete one full oscillation.
• Calculate 'g' using the formula: g = 4π²l / T², where 'l' is the length of the pendulum and 'T' is the time period.

 

Experiment 2: Determination of the Coefficient of Viscosity of a Liquid

Question: 2. Describe the apparatus and method for determining the coefficient of viscosity of a liquid.

Answer: To determine the coefficient of viscosity of a liquid, you will need:

• A capillary tube
• A liquid of known density
• A stopwatch
• A meter rule
• A clamp stand

Method:

• Fill the capillary tube with the liquid and place it vertically in a clamp stand.
• Measure the distance moved by the liquid meniscus in the capillary tube in a specific time interval.
• Calculate the coefficient of viscosity using the formula: η = 2r²(ρ₁ - ρ₂)g / 9L(vt).

 

Experiment 3: Determination of the Focal Length of a Concave Mirror

Question: 3. Explain how to determine the focal length of a concave mirror.

Answer: To determine the focal length of a concave mirror, follow these steps:

• Set up the experimental apparatus, including the concave mirror, a screen, and a light source.
• Move the screen back and forth until a sharp, inverted image of the light source is formed on the screen.
• Measure the distance between the mirror and the screen; this is the focal length (f) of the mirror.

 

Tips for WAEC GCE Physics Practical Success

1. Practice Regularly: Consistent practice is key to mastering physics practical experiments. Set up your own experiments at home to gain hands-on experience.

2. Understand Concepts: Ensure you have a solid grasp of the theoretical concepts behind each experiment. This will make it easier to answer related questions.

3. Time Management: During the exam, allocate your time wisely. Don't spend too much time on a single experiment. If you get stuck, move on to the next and come back later.

4. Use Proper Units: In your answers, be sure to include the correct units for measurements. This attention to detail can earn you extra points.

5. Review Previous Papers: Go through past WAEC GCE Physics Practical papers to familiarize yourself with the type of questions that are likely to appear.

 

Conclusion

Success in the WAEC GCE 2023/2024 Physics Practical Exam is achievable with the right preparation. By practicing and understanding the experiments thoroughly, you can approach the exam with confidence. Remember that a good understanding of the concepts, as well as the ability to perform practical experiments accurately, are essential for excelling in this examination.
