### What type of mirror is used for shaving?

When a concave mirror is used as a shaving mirror, where is the face of a man in relation to the focus of mirror? State the characteristics of the image seen.

Why convex mirror is used in shaving?

The shaving mirrors are used to view the enlarged image of the face. To view the enlarged image of the face we should use concave mirrors because they form a virtual, erect, and enlarged image when an object is placed near the mirror (between pole and focus).

#### Why is concave mirror used as shaving mirrors?

The concave mirrors are used as shaving mirrors because when the face is held within the focus of concave mirror then an enlarged image of the face is seen in the concave mirror.

Which type of mirror is used in torch and shaving mirror?

So, what is the use of a concave mirror? Well, various objects that we see around like vehicle headlights, Shaving mirrors, Solar furnaces, Searchlights, torches, flashlights, and so on. All these objects have a concave mirror.

## Which property of concave mirror is used in shaving mirror?

Solution : When an object is held between the pole and principal focus of a concave mirror, a virtual, erect and magnified image of the object is formed. This is the property utilized for using them as shaving mirrors.

Which characteristics of concave mirror is used in shaving mirror?

The face has to be held between the focus and pole of the concave mirror. This makes the image as erect, enlarged and virtual and formed behind the mirror.

### Why shaving mirrors are concave mirrors?

Concave mirrors are used as shaving mirrors because when the face is placed close to a concave mirror (within the focus of the mirror) it produces a magnified and erect image of the face. Since an enlarged or magnified image of the face can be seen in the concave mirror, it becomes easier to make a smooth shave.

Why concave mirror is used for makeup or shave?

#### Are convex mirror used in torches?

Thus when it is used in torches, car reflectors and street lamps, it would diverge the falling rays and thus spread the light and increase the visibility area. Therefore, torches and car reflectors use convex mirrors.

When concave mirror is used as shaving mirror the position of the face should be?

As shown in figure a concave mirror forms virtual and magnified image when object is between POLE and FOCUS so clear magnified view is seen while shaving. So object (shaving face) should be between POLE and FOCUS.

## When a concave mirror is used a shaving mirror it must have a ___ focal length?

A concave shaving mirror is of focal length 50cm.

Which mirror is used as shaving mirror and why explain with diagram?

Answer: Concave mirrors are used as shaving mirrors. This is because when the face is placed close to a concave mirror (so that the face is within its focus) the concave mirror produces a magnified and erect image of the face.

### Is a makeup or shaving mirror convex or concave why Where is your face relative to the focal point of the mirror?

Mirrors which are used for shaving and for make up are concave ones. They are used because if the face is positioned at the right distance from the mirror, image will be upright and magnified, and that location is within the focal length.

Why is concave mirror used in solar cooker?

The reasons for using a concave mirror in solar cookers are given below: Concave mirrors absorb all the incident light and reflect it to a single focal point. This reflected light is very powerful because it carries a lot of thermal energy. The cooking pot is placed on the focal point where the light is concentrated.

#### What is the example of convex mirror?

Magnifying glasses, telescopes are examples of convex mirrors.

What type of mirror is used as shaving mirror and in what position the object must want to be placed in this case?

Answer. A concave mirror produces a virtual and magnified image when the object is placed very close (between P and F, or between C and F) to it. This position should be used for shaving mirror.

## Which of the following figure shows the use of a concave mirror as a shaving mirror?

Solution : When an object is held between the pole and principal focus of a concave mirror, a virtual, erect and magnified image of the object is formed. This is the property utilized for using them as shaving mirrors. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

Why concave mirror is used as shaving mirror with diagram?

### How about the concave mirrors that are often used as shaving mirrors and makeup mirrors?

A person who is shaving keeps his face closer to the centre of the mirror, that is between the pole and the focal point. Hence, it appears enlarged. This is the reason why concave mirrors are used as shaving and makeup mirrors.

Can convex mirror be used in solar cookers?

If we use a convex mirror for your cooker, it will not work since they do not have a focal point. A flat mirror, on the other hand, doesn’t have a focal point; it reflects off all of the incident light on different points which means that it cannot be used to harness solar energy.

#### Why are convex mirror used in solar devices?

A converging mirror such as a convex mirror does not have this capacity and a plane mirror doesn’t even have a focus point. The concave mirror can absorb maximum sunlight which is incident on it to its focus which carries very powerful thermal energy.

What is the example of convex polygon?

Real-world examples of convex polygons are a signboard, a football, a circular plate, and many more. In geometry, there are many shapes that can be classified as convex polygons. For example, a hexagon is a closed polygon with six sides.

## What are 3 examples of concave mirrors?

Some concave mirror uses are listed in the points below.

• Shaving mirrors.
• Ophthalmoscope.
• Astronomical telescopes.
