Learning Area Multiple Choice. Select the letter of the best answer from among the given choices and write your answer before each number.
1. In reflection, how is the wave theory of light related to particle theory of light?
A. They complement each other
B. They are contradicting each other
C. There is no difference between the wave theory and particle theory of light. D. Together, they show that reflection is popular than refraction.
2. Which of the following best describes the refraction phenomenon?
A. It is explained better using the wave model of light than the particle model of light.
B. It is explained using the photon theory of light.
C. The particle model predicts that particles of light will speed up as they pass through the boundary between air and water.
D. The wave model correctly predicts that light will slow down as it passes through the boundary between air and water
3. How do we see a tree?
A. The light that reaches our eyes has been reflected by the tree.
B. The light that reaches our eyes has been refracted by the tree
C. The light that reaches our eyes has been separated into a spectrum by the tree.
D. The light that reaches our eyes has undergone interference in passing through the tree
4. In photographic darkrooms, what is the reason why red light is used?
A. Most of the photographic films are not sensitive to red light
B. Photographic paper is not sensitive to white light
C. The frequency for red light is low hence the energy of the photos is less
D. The frequency of the red light is high hence the energy of the photos is high.
5. Eshf is an equation that describes the relationship between the energy (E) and frequency of light (f). Why do we easily get sunburned in ultraviolet light but not invisible light?
A Ultraviolet light is of higher frequency than visible light; therefore, it has higher energy and is sufficiently energetic to cause skin damage,
B. Ultraviolet light has longer wavelengths than visible light; therefore, it has lower energy and is sufficiently energetic to cause skin damage
C. Ultraviolet light has shorter wavelengths than visible light, therefore, it has higher energy and is sufficiently energetic to cause skin damage
D. Ultraviolet light is of lower frequency than visible light; therefore, it has lower energy and is sufficiently energetic to cause skin damage
6. He formulated the hypothesis that electron being a particle has wave-like characteristics.
A. Albert Einstein
C. Louis de Broglie
B. Max Plank
D. Neils Bohr
7. Which property of light is responsible for the silver lining at the edges of the clouds?
A. Dispersion C. Interferenc
e B. Scattering D. Diffraction
8. It is natural occurrence produced by the refraction of light as it travels between hot and cold air.
A. mirage C. virtual image
B. myriad D. real image
9. Which of the following situations exemplifies the dispersion property of light? 1​
