23. Which of the following is not true? * 0 Electric potential energy is not equal to voltage Measurement of the voltage requires measuring the electric potential energy in two points in a circuit. 0 Electric potential energy is analogous to the gravitational potential energy, a stored energy that can be used later as kinetic energy of charge particles. Potential energy difference or voltage across a resistor is all converted into heat 24. Which of the following is true about the formation of a rainbow? * O A rainbow is the manifestation of reflection of light 0 A rainbow is formed when visible light is separated from the rest ofthe electromagnetic spectra 0 A rainbow is formed when there is separation of the visible light waves with different wavelengths hence different refractive indexes and velocities in a certain medium 0 A rainbow is formed when a medium absorbs all other electromagnetic waves except visible light 25. If the magnification (m) is negative, the image is said to be . * 0 Reduced O Enlarged 26. An object's ray of light enters a plain transparent glass with higher index of * refraction then goes baok to the air. What can you say about the image if the object is viewed in the other side as shown in the figure below? / {V O The object appears higher than it's real location 0 The object appears exactly where it is located 0 The object appears lower than it's real location 0 No image is formed 2?. Which of the following statements is not true? * 0 Mirrors form images via reflection while lenses form images via refraction 0 Mirrors have one focal point while lenses have two fecal points 0 The height of the images formed by any type of mirrors are always equal to the height of the actual object while lenses can reduce or enlarge images. 0 None of the above 28. If the focal length of the lens is negative that means . * O The lens is a diverging lens 0 The lens is a converging lens 0 The focal point is in the left or negative x-axis O The image must be in the left
