What is the rule for the reflection RX axis XY?

question. The rule of reflection are: ry-axis (x,y) to (-x,y) (Option B)

What is the rule for this reflection?

Quote from video:The coordinates become negative X Y if you're reflecting over the x axis.

Which reflection of the point will produce an image located at 0 m )?

Therefore the reflection of the point (m,0)and m≠0 will produce an image located at (0,-m) when reflection occurs across the line y=(-x).

What are the 4 rules for reflection?

Reflection on a Coordinate Plane

• Reflection Over X Axis. When reflecting over (across) the x-axis, we keep x the same, but make y negative. …
• Reflection Over Y Axis. When reflecting over (across) the y-axis, we keep y the same, but make x-negative. …
• Reflection Across Y=X. …
• Reflection Across Y=-X.

What are the two rules of reflection?

Laws of reflection are: (i) The incident ray, the reflected ray and the normal ray at the point of incidence, lie in the same plane. (ii) The angle of incidence is equal to the angle of reflection.

What are the 3 laws of reflection?

The incident ray, the normal and the reflected ray are all in the same plane. Changing the direction of the incident ray changes the angle of the plane. Again the incident ray, the normal line and the reflected ray all lie in the same plane.

What are laws of reflection and refraction?

1- Incident ray, reflected ray and normal will lie in the same plane. 2- Angle of incidence will be equal to the angle of reflection. Laws of Refraction- 1- Incident ray, reflected ray and normal will lie in the same plane. 2- Refraction depends on the medium through which the light rays travel.

What are the 4 rules of concave mirror?

Rules for Obtaining Images Formed by a Concave Mirror

• A ray coming parallel to the principal axis is reflected through the principal focus of the concave mirror. …
• The ray of light passing the principal focus becomes parallel to the principal axis after being reflected from the mirror.

What are rules of mirror?

They are: Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection. Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.

What are rules of convex mirror?

For a convex mirror, if the object is at infinity the image will be a dot on the focal point. As the object moves from infinity toward the mirror, the image moves along the principal axis toward the mirror. When the object is right next to the mirror, the image will be right next to the mirror on the other side.

What are the rules in concave and convex mirrors?

When a ray, parallel to principal axis strikes concave or convex mirrors, the reflected ray passes through the focus on the principal axis. When a ray, passing through focus strikes concave or convex mirrors, the reflected ray will pass parallel to the principal axis.

How many rules does a convex mirror have?

Once these incident rays strike the mirror, reflect them according to the two rules of reflection for convex mirrors. The ray that travels towards the focal point will reflect and travel parallel to the principal axis. Use a straight edge to accurately draw its path.

How many rules does a concave mirror have?

Rule 1: An incident ray traveling parallel to the principal axis creates a reflected ray that passes through the principal focus of the concave mirror. Rule 2: An incident ray of light passing through the principal focus of a concave mirror creates a reflected ray that is parallel to the principal axis of the mirror.

What are the rules for ray diagrams?

Rules for drawing Ray Diagram in Lenses

• Rule 1 – Ray parallel to principal axis will pass through focus. For a convex lens , …
• Rule 2 – Ray passing through focus will become parallel to principal axis. For a convex lens, …
• Rule 3 – Ray passing through Optical Center will emerge without deviation.

How many rules are there in ray diagram?

Thus, merely construct a ray diagram to determine the image location; use the two rules of reflection. Then draw the reflected rays for the two given incident rays through the same image point.

What are the three rules for the drawing ray diagrams formed by spherical mirrors?

Any ray of light that passes through the mirror, is always parallel to the principal axis. Any ray of light that passes through the mirror always passes through the principal focus (f) of the mirror after reflection.

What are the rules for drawing a ray diagrams Class 10?

Rules used for drawing ray diagrams for the formation of an image by a convex lens : (1) When the incident ray is parallel to the principal axis, the refracted ray passes through the principal focus. (2) When the incident ray passes through the principal focus , the refracted ray is parallel to the principal axis.

What are the rules for obtaining image formed by concave mirror?

Table 5: Rules for image formation by concave mirrors.



Image Formation by Concave Mirrors.

Which laws are used for drawing ray diagrams for image formation in a mirror?

Answer: The correct option is option b) Laws of reflection.

What are the rules used for drawing ray diagrams for the formation of image by convex lenses?

Explanation: Rule 1 : when the incident ray is parallel to the principal axis, the refracted Ray passes through the principal focus. Rule 2 : when the incident ray passes through the principal focus, the refracted ray is parallel to the principal axis.

What are the rules for drawing rays for a converging lens?

Quote from video:So that's our first rule. Our second rule is that if we have a light ray that's moving through the optical. Center it will continue on in the exact.

How do you draw a ray diagram for refraction?

Quote from video:So we can draw that ray of light on and again we can put an arrow showing the direction of the red light and that means that within the block. The ray of light must have traveled along that path.
