For a total internal reflection, which of the following is correct?
If the angle of incidence is $70^o$, then calculate the angle between the incidence ray and the reflected ray.
Which objects use the reflection of light?
An ideal mirror :
Which of the following statement is/ are correct?
I. A person suffering from myopia can see distant obhects clearly.
II.. The bluish color of water in deep sea is only due to reflection of sky in water.
III. In vacuum, all the colored of the light move with the same speed.
IV. At noon, the sun appears white as light is least scattered
The laws of reflection are true for
Shaving mirrors are
If a ray of light incident on a plane mirror is such that it makes an angle of $30^{\circ}$ with the mirror, then the angle of reflection is
The angle between the original path of the incident ray and the emergent ray coming out of a prism is called angle of
The phenomenon that leads to the bouncing back of light rays is called-
The phenomenon in which light that strikes a surface is thrown back into the same medium is called -
The bouncing of a beam of light from a polished surface in some other direction is called -
According to the laws of reflection, angle of incidence is equal to angle of reflection.
The phenomenon by which the incident light falling on a surface is sent back into the same medium is known as ___________.
Which objects use the reflection of light?
Read the given statements and select the correct option.
Statement 1: When a ray of light passes from air into water, it will bent towards the normal.
Statement 2: When light travels from air into water, its speed increases.
Riya and Priya were sitting around a round table. They noticed that they could see their own and each other's image onto the table top. Then table top is made of
Reflection is
The locus of a point which moves so that its distance from x-axis is double of its distance from y-axis is
A ball of $1\ g$ released down an inclined plane describes a circle of radius $10\ cm$ in the vertical plane on reaching the bottom. The minimum height of the inclined plane is
If a ray of light passes from a denser medium to a rarer medium in a straight line, the angle of incident must be _____
While is not basic transformation function
A ray of light is incident on a plane mirror along a vector $\hat i+\hat j-\hat k$. The noemal on incident point is along $\hat i+\hat j$. Then unit vector along the reflected ray is:
