When light falls on an object, it
may be transmitted (allowed to pass through it without interaction)
, or reflected (the ray is turned back without allowing it to pass through), or it is absorbed (used up completely for any one or more of the transitions listed in the tables given below) or it is scattered (reflected …
What happens when light falls on an object class 6?
Answer: When light falls on a non-luminous object,
it reflects light in different directions
. When this light reaches our eye, we are able to see the object.
What will happen to the light which falls on a surface of an object class 10?
Reflection Of Light: When a ray of light falls on polished surface,
it turns or reflects most of the light in the same medium from which it comes
. This phenomenom is known as reflection of light. (ii) The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane.
What happens when light falls on an object class 7?
Answer:
The light wave could be absorbed by the object
, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object.
What happens when light falls on a transparent object?
Materials like air, water, and clear glass are called transparent. When light encounters transparent materials,
almost all of it passes directly through them
. … The light does not pass directly through the materials. It changes direction many times and is scattered as it passes through.
What 3 things happen to light when it hits a surface?
What happens when light hits a different material? Light travels in straight lines through a material (like air) until it hits a different material. Then
it can be absorbed reflected or
• Then, it can be absorbed, reflected, or transmitted (which means “passed through”).
What two possible phenomenon can happen when light falls on a surface?
Possible phenomenon happen when light falls on a surface are
Absorption,Reflection, Scattering,Refraction
.
What is the mirror formula?
Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation;
1/f= 1/u + 1/v
. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.
What are the 7 properties of light?
- Reflection of light.
- Refraction of light.
- Diffraction of light.
- Interference of light.
- Polarization of light.
- Dispersion of light.
- Scattering of light.
What is concave mirror Class 7?
A concave mirror
produces a smaller, bigger and inverted image based on its distance from the object
. When the distance between object and mirror is large, a small inverted virtual image is formed. As the object is brought closer, the image becomes larger.
What are the 3 properties of light?
The primary properties of visible light are
intensity, propagation-direction, frequency or wavelength spectrum and polarization
.
Can light be reflected from a transparent object?
There is, however, a phenomenon called
“total internal reflection”
where a transparent object can reflect ALL light that approaches its boundary within a certain range of angles. This is what causes the strange reflection you see when looking up from under water near the surface and how fiber optic systems work.
What do you call an object that makes its own light?
Lesson Summary.
Luminous sources
are objects that emit their own light, and luminosity is the amount of light that a luminous source provides. A candela is the unit of measurement for luminosity.
Do opaque objects absorb light?
Light cannot shine through opaque materials at all. In fact,
opaque materials absorb the light that shines on them
. A little of the light is reflected back, though. Each object reflects some light waves of a certain color.
Which would light travel through fastest?
Explain that unlike sound, light waves travel fastest through
a vacuum and air
, and slower through other materials such as glass or water.
What happens when light falls on a smooth polished surface most of it?
When light falls on a smooth polished surface, most of it is
reflected in the same direction
., and this type of reflection is known as regular or specular reflection.
