The phenomenon in which light that strikes a surface is thrown back into the same medium is called -

0%
reflection
0%
reflex action
0%
refraction
0%
regression

Explanation

R e f l e c t i o n

$\bf{Reflection}$ is the phenomenon in which light rays on striking a polished surface(such as a mirror) bounce back or are sent back into the same medium.

$\bf{Reflex\ action}$ is an involuntary and nearly instantaneous movement in response to a stimulus.

$\bf{Refraction}$ of light is the phenomenon of bending of light or change in the direction of light, when it passes obliquely from one transparent medium to another.

$\bf{Regression}$ is a technique for determining the statistical relationship between two or more variables where a change in a dependent variable depends on the change in one or more independent variables.

Hence, the correct answer is OPTION A.

The phenomenon that leads to the bouncing back of light rays is called-

0%
Diffraction
0%
Reflection
0%
Dispersion
0%
Refraction

Explanation

$\bf{Diffraction}$ is the phenomenon of bending of light waves around the corners of an obstacle or aperture, placed in the path of light beam.

$\bf{Reflection}$ is the phenomenon in which light rays on striking a polished surface(such as a mirror) bounce back or are sent back into the same medium.

$\bf{Dispersion}$ is the phenomenon of splitting of white light into its component colours (VIBGYOR) on passing through a glass prism.

$\bf{Refraction}$ of light is the phenomenon of bending of light or change in the direction of light, when it passes obliquely from one transparent medium to another.

Hence, the correct answer is OPTION B.

The term reflection refers to the bending of light rays:

0%
when they strike a mirror
0%
when they enter a different medium
0%
around a sharp edge
0%
around the boundary of a narrow aperture

Reflection is the ........ of light off a surface.

0%
Bouncing
0%
hitting
0%
firing
0%
all

Explanation

Reflection is the $bouncing$ of light off a surface.

Opaque objects:

0%
do not transmit most of the light falling on them
0%
transmit most of the light falling on them
0%
absorb most of the light falling on them
0%
are strong and hard

Diamond is :

0%
transparent
0%
translucent
0%
opaque
0%
semi-absorbent

Explanation

$\bullet$ Objects which allow the light to pass through them completely without any obstruction are called

$\bf{transparent}$ objects.

$\bullet$ Objects which allow the light to pass through them partially are called

$\bf{translucent}$ objects.

$\bullet$ Objects which do not allow the light to pass through them are called

$\bf{opaque}$ objects.

$\bullet$ Since a diamond allows the light to pass through it completely without any absorption or obstruction of light, it is a transparent object.

Hence Option A correct

State whether true or false.

The bouncing of a beam of light from a polished surface in some other direction is called -

0%
refraction
0%
reflection
0%
dispersion
0%
scattering

Explanation

$\bf{Refraction}$ of light is the phenomenon of bending of light or change in the direction of light, when it passes obliquely from one transparent medium to another.

$\bf{Reflection}$ is the phenomenon in which light rays on striking a polished surface(such as a mirror) bounce back or are sent back into the same medium.

$\bf{Dispersion}$ is the phenomenon of splitting of white light into its component colours (VIBGYOR) on passing through a glass prism.

$\bf{Scattering}$ is the phenomenon by which a beam of light is redirected or deflected in many different directions, when it passes through an imperfect medium, due to interaction with the particles of the medium.

Hence, the correct answer is OPTION B.

Pinhole camera is a simple application of :

0%
reflection of light
0%
rectilinear propagation of light
0%
refraction of light
0%
scattering of light
