The Behavior of Light: Wave and Particle Models
Light is a fascinating phenomenon that can be explained through both the wave and particle models. The wave model describes light as an electromagnetic wave that travels through space, while the particle model considers light as composed of tiny packets of energy called photons. These two models help us understand how light propagates, reflects, and refracts.
One of the key aspects of light is its ability to spread out and interact with surfaces. When light encounters a smooth surface, such as a mirror, it follows the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This means that if a light ray strikes a mirror at an angle of 10° from the normal, it will reflect back at the same angle of 10°. This predictable behavior allows us to see our reflections in mirrors.
Light also behaves differently when it passes through transparent materials like water or glass. This bending of light is known as refraction. The amount by which light bends depends on its wavelength. Visible light, which is part of the electromagnetic spectrum, is composed of different colors, each with a unique wavelength and energy level. Among these, red light has the longest wavelength and the lowest energy, while blue light has a shorter wavelength and higher energy. This difference in wavelength is also responsible for the arrangement of colors in a rainbow.
Rainbows form when sunlight passes through raindrops, undergoing both reflection and refraction. Because red light has the longest wavelength, it is refracted the least and appears on top of the rainbow, while blue light, which has a shorter wavelength and is refracted more, appears at the bottom. This natural display of colors beautifully demonstrates how light behaves when it interacts with water droplets in the atmosphere.
By understanding the wave and particle models of light, we can explain the different ways in which light moves, reflects, and refracts, shaping the way we see and interact with the world around us.

1. A light bulb produces various wavelengths of energy called light spectrum. The visible light is the segment of electromagnetic spectrum that is visible to human eye. Which of the following colors of the visible light spectrum contains the lowest amount of energy?
A. blue
B. green
C. red
D. yellow

2. What is the angle of reflection made by a light ray that is incident at 10° on the mirror, as shown in the figure below?

A. 10° C. 90°
B. 80° D. 110°

3. Why is red colour always seen on top while blue is at the bottom of a rainbow?
A. Red has a long wavelength so it moves faster and is refracted the least by water droplets in the air.
B. Blue has a long wavelength so it moves faster and is refracted the most by water droplets in the air.
C. Blue has a short wavelength so it moves faster and is refracted the most by droplets of water in the atmosphere.
D. Red has a short wavelength so it moves faster and is refracted the least by droplets of water in the atmosphere.

Earthquake Magnitude and Intensity: Understanding Their Differences and Effects

Earthquakes are natural events that result from the sudden movement of the Earth's crust. When discussing earthquakes, two important terms are often used: magnitude and intensity. Magnitude refers to the amount of energy released at the earthquake's source, measured using the Richter Scale or Moment Magnitude Scale (Mw). For example, a Magnitude 4.0 earthquake is generally weak and may only cause minor shaking, while a Magnitude 7.0 or higher earthquake can lead to severe damage. On the other hand, intensity describes the actual effects of an earthquake on the Earth's surface, including the shaking felt by people and damage to structures. In the Philippines, intensity is measured using the PHIVOLCS Earthquake Intensity Scale (PEIS), which ranges from Intensity I (Scarcely Perceptible) to Intensity X (Completely Devastating). Unlike magnitude, which remains constant, intensity varies depending on location and local ground conditions.

The effects of earthquakes on the environment and communities can be devastating. In areas where shaking is measured at Intensity VI (Very Strong) on the PEIS, damage to poorly built structures is expected, while Intensity VIII (Very Destructive) can lead to landslides, ground rupture, and severe structural failure. Earthquakes can damage roads, bridges, and buildings, leading to casualties and significant economic losses. Utility systems such as power lines, gas pipelines, and water supply networks may also be affected, increasing the risk of fires and water shortages. In rural areas, earthquakes may alter river courses, destroy farmlands, and trigger landslides. The level of destruction depends on the earthquake’s magnitude, the preparedness of the affected region, and the quality of infrastructure.

TWO PRINCIPLES OF DEMOCRACY

1). Individual autonomy- People should be able to control their
OWn lives.

2). Equality- Everyone should have the same opportunity to influence the decisions that affect people in society.
-------------

Choose one of the two Principles of Democracy above. Give an example that is evident in our current society.
