Light and their characteristics

1. LIGHT WAVE AND THEIR CHARACTERISTICS

2. Relate characteristics of light such as color and intensity to frequency and wavelength; and Participate in the class activities and class discussion, and Take and pass the quiz with a mastery level of 75%.   OBJECTIVES

3. “Light is a form of electromagnetic radiation and is responsible for the sense of sight.” LIGHT

4. “Plato thought that light consisted of streamers emitted by the eye.”

5. “Christian Huygens who explained the reflection of light using wave motion.”

6. “Isaac Newton contradict the wave theory as he described light as a stream of particles or corpuscles.”

7. “Thomas Young in his experiment in 1801, was able to study that interference and diffraction of light.”  

8. “Max Planck introduced the phenomenon known as blackbody radiation, which, according to him, was emitted in discrete bundles of energy called quanta (plural for quantum).

9. “Arthur Compton’s study of the scattering of X-rays by electrons all required the assumption of a particular nature for electromagnetic radiation without I any way invalidating the wave theory of light.”

10. “A wavelength (which varies inversely with frequency) manifests itself as color, while wave amplitude is perceived as luminous intensity or brightness; it is measured by the standard unit of a candela.”

11. “Candela is the fundamental unit of luminous intensity.”

12. “Brightness is a qualitative expression of light intensity. It is the visual perception in which a light source appears to be emitting light or a surface appears to be reflecting light."

13. "Dispersion A phenomenon in which a prism separates white light into its component colors.”
