emergency vehicles. Red color is being chosen as the color for the emergency vehicles strobe lights is because of the night vision capability by using this color. It cannot be denied that red color is more easily to be notice if compared to other color. Red color can catch more attention and alert when we saw red because red is signal us about danger. Advantages and Disadvantages White: light is the most effective attention-getting signal‚ containing all visible spectral wavelengths

Purpose: To investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero‚ there would be no refraction. When the light passes at an angle from air into an optically denser medium‚ the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0. Method:

Some terms related with reflection are – 1. Incident Ray - The light ray striking a reflecting surface is called the incident ray. 2. Reflected Ray – The light ray obtained after reflection from the surface in the same medium in

Let it Snow In the reading‚ “Let it Snow” the author tries to convey a very strong approach. The story makes certain points within the children and the mother. The story talks about how the children had a few snow days in a row and they were extremely excited about it. Come to find out‚ the mother was not excited at all. The children take different approaches to try and get the mother to come outside and let them back in the house. There are several different symbols in the story‚ also there is meaning

Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

Sinclair Ross responds to the issue of isolation‚ in his short story‚ "The Lamp at Noon." The author focuses on the theme of how not to deal with isolation. This notion is reinforced by the setting (mood/physical)‚ characters‚ and symbolism that he describes so vividly. The first method the author uses to convey the idea of isolation is through setting. The setting was beautifully described creating imagery that assists the focus of the theme. Sinclair expresses personification in climate changes

specific objects around the room with out moving their body or heads and then leading into the discussion. This section I believe confused a lot of students because it started to lead to the misconceptions that a lot of students have about this topic of light‚ that we did not intend to happen. My Second student I chose for observation gave evidence as to why I think this is true. The student said‚ “My eyes couldn’t see behind me‚ because In the past I have seen the objects behind me‚ I couldn’t see them

Conclusion: Explain‚ in your own words‚ why different elements produce different colors of light when heated. Each element has a unique electron configuration. When heated‚ the electrons are energized and this leads to a higher quantum state. The color depends on the distance you have and the original electron configuration. Why do you think elements must be heated before they emit colored light?The light color is the electronic transitions between orbitals. When an electron drops to a

Light Emission and Absorption - Active Reading When atoms absorb energy‚ electrons can jump to higher energy orbitals. When the electrons move back to their original configurations‚ that energy is given off as light! Travel to the website linked below and take Cornell notes for each section.
