LaserMeasure and Level tool

Choose among our selection of Bosch, DeWalt, Datum, Milwaukee, and Makita laser measurers that are ideal for jobsites, workshops, and garages. Some models feature a 6m range to 60m, 40m beam range, and 10m/s measurement speed. The built-in red or green beam is visible over long distances and has an IP54 rating to protect against water splashes. Others even come with continuous measurement functions, integrated tape measures, Pythagoras and double Pythagoras calculations, and addition/subtraction functions. These tools also come with an auto switch-off function so you will always have fresh power and longer battery life.

A. The law of reflection is valid for all the reflecting surfaces including plane mirrors, concave mirrors and convex mirrors. Concave and convex mirrors have curved surfaces but at the microscopic level it can be considered to consist of an infinite number of a plane reflecting surfaces.

The reflecting surface can be plane or spherical. In the above figure, a plane reflecting surface is shown. A parallel beam of light incident on the surface after the reflection is bounced back in the same medium.

A. Yes, water can reflect light. Also, it refracts the light. When the light falls on the water surface some of the light gets reflected and some refracted into it.

There are two laws that govern the reflection of light (reflected from any surface). These Laws are referred to as laws of reflection. When light from any object reflects from polished surfaces, the reflection is called regular reflection. Regular reflection produces an image. We obtain two different types of images: real and virtual, depending on the mirror (reflecting surface) and object position.

At home, we create our virtual image using plane mirrors. The image distance from a plane mirror will be equal to the object distance from the mirror. The light ray is reflected by a planar surface and is subject to the following two laws of reflection.

When a light ray encounters a boundary between two different media and bounces back to enter the same medium, this phenomenon is referred to as the reflection of light. The ray which falls on the surface is called the incident light ray. The ray that bounces back is known as the reflected ray. If we draw a perpendicular on the reflecting surface, at the point of incidence it is called the normal. The point where a light ray coming from an item or source appear to meet after being reflected by a surface is called an image. We can see our surroundings because light reflects off a variety of surfaces.

Let's play an interesting game. First, keep your face in front of a dull wall and observe. Now see your face on your shining floor and note the observation. Now take a bucket of water and see your face in it and observe. At last, see your face in the plane mirror at your home. If you compare the observations of all four cases you will find there is no image of your face when you see it on the wall. There is an image with very poor quality when seen on the floor. When you see the face in the water still you can see the image but not clear. You got a proper image of good quality when seen in the plane mirror. Although all four are plane surfaces, still we are getting different quality images. This phenomenon can be understood by the reflection of light. The walls of the house are rough in nature so produce diffuse reflection and regular reflection is very less when light falls on it. On the other hand, the mirror reflects almost all the light that falls on it. Let's learn more about the reflection of light!

Object : An object is everything which is viewed. Also it is the point of intersection of the incident rays. The object can be real and virtual. When the incident rays actually meet (or emerge from) the object is called a real object (figure 1). When the incident rays appear to meet (or emerge from) then it is called a virtual object (figure 2).

Shop from our range of professional and high-quality laser measurers at Total Tools! These test and measurement tools feature super bright red or green beam that is highly visible, scratch-resistant LCD screens, and real-time length, area, and volume. The default real-time measurement shows how distances move with the target.

Image : The point of intersection of reflected rays is called image. It can also be real and virtual. If the reflected rays appear to meet then it is called a virtual image (figure 1). If the reflected rays actually meet at a point then it is called real image (figure 2).

A. The light coming from the sun falls on the moon and after the reflection from the moon it reaches the earth and thus we can see it. The portion on which the light falls appears bright and the rest appears dark.

A. Compared to objects with dull or unpolished surfaces, glossy or polished objects reflect more light. The best light reflector is made of silver metal.
