Direct the light reflected by the mirror on to a sheet of paper held close to the mirror. Move the sheet of paper back and forth gradually until you find on the paper sheet a bright, sharp spot of light. Hold the mirror and the paper in the same position for a few minutes.
Electromagnetic waves are distinguished from each other by their differences in wavelengths and frequencies (wavelength is inversely related to frequency). c=fλ c = speed of light = 3.0 x 10 8 m/s in a vacuum = 300,000 km/s = 186,000 miles/s. A light year is the distance that light travels in one year in a vacuum.

S4-5)PS4.A: Wave PropertiesThe wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium. through wh. Information can be digitized (e.g., a picture stored as the values of an array of pixels); in this form, it can be stored.
In this module you will learn about the nature and properties of light in the following lessons: Lesson 1 – The Nature of Light Lesson 2 – Reflection and Mirrors Lesson 3 – Refraction and Lenses Lesson 4 – Colors, Interference and Polarization. What you are expected to learn.
Following are the important properties of light –. Light travels in a straight line. The speed of light is faster than sound. Light travels at a speed of 3 x 10 8 m/s. Reflection of light. Reflection is the phenomenon in which light travelling in one medium, incident on the surface of another returns to the first medium, obeying the laws of ...
When light propagates in a transparent material medium, its speed is in general less than the speed in vacuum c. An interesting consequence of this is that a light ray will change direction when passing from one medium to another. Since the light ray appears to be “broken”, the phenomenon is known as refraction.

ight and Optics:We just learned that light is a wave (an "electromagnetic wave", with very s. all wavelength).But in many cases, you can safely ignore the wave. nature of light!Light was studied for a long time (obviously), long before Maxwell, and very. well understood. People thought about light as sort of like a stream of "particles" that ...
