Reflection Of Light Explained
What are Reflection and Refraction of Light?
Reflection of Light: Bouncing back of the light from the surface of an object after falling on it, is called the reflection of light.
Ray of light falling on the surface is known as Incident Ray and Ray of light Reflecting (bouncing) back from the surface is known as Reflected Ray. Angle formed by Incident Ray with Normal is known as Angle of Incident (i) and angle formed by Reflected Ray with Normal is known as Angle or Reflection (r);
For example; we see objects due to reflection of light. When light falls on an object, part of it reflects back in to all directions and when these reflected rays of light enter our eyes and reaches to retina of eyes, which sends electrical signals to brain which register the image of the object. It happens so fast that we can’t record the time lag.
When the surface is smooth and shiny (like glass, water and shiny metals) then angle of reflection is equal to angle of incident, such reflection is known as specular reflection. Light rays after reflection travel into same direction.
When the surface is rough the light scatters into all directions and such reflection is known as diffuse reflection.
When lake water is still then we can see clear image of the surrounding landscape due to reflection of light from water surface.
For elementary school kids:
Can you write about reflection in you own words? What is specular reflection and diffuse reflection?
great tutorial.. thanks @mathworksheets
You are the best dear @dinsha :))
Now, this should be taught in the elementary school for photographers! Excellent, @mathworksheets!
Ha hahaaa! You know this topic much better than me my dear friend :)
