Why is a beam of light wider and dimmer when it hits a wall than when it leaves the flashlight?
Wiki User
∙ 11y ago
When the beam of light hits a wall, it spreads out due to a process called diffraction, which causes the light waves to bend around the edges of the obstacle. This spreading of light results in the beam appearing wider and dimmer compared to when it leaves the flashlight as a more focused and intense beam.

What describes the light waves that make up laser light?
Laser light is made up of coherent and monochromatic light waves. Coherent means that all the light waves are in phase with each other, and monochromatic means that the light consists of a single color or wavelength. This allows laser light to be focused into a tight beam with high intensity and precision.
Would orange light or blue light produce a wider diffraction pattern?
Blue light would produce a wider diffraction pattern compared to orange light. This is because smaller wavelengths diffract more than larger ones when passing through an aperture, resulting in a wider spread of light.
Do convex mirrors focus light?
Convex mirrors do not focus light, but instead they diverge the light rays that hit them. This causes the reflected light rays to spread out which results in a wider field of view.
How you explain the closer the light source to the object the larger the shadow?
When the light source is closer to the object, the light rays diverge less, resulting in a sharper shadow. This is because the object blocks more of the light rays when the source is closer, creating a larger shadow relative to the object's size. The distance between the light source and the object affects the size and sharpness of the shadow cast.
What is the light beam size regulated by?
The size of a light beam is regulated by the aperture of the lens or the diameter of the opening through which the light passes. A smaller aperture will create a narrower and more focused beam of light, while a larger aperture will create a wider beam.
What describes the light that makes up laser light?
The waves get wider and dimmer as they move.

What is the difference between obovate and ovate leaf?
An obovate leaf is wider toward the tip, while an ovate leaf is wider at the base and tapers to a pointed tip. Obovate leaves are inverted ovate leaves, with the wider part near the apex.
What causes our winter spring fall summer and what point are they opposite?
Since the Earth is on an axis, the distribution of the light on Earth varies throughout the year. For example, when you hold a flashlight directly over the floor, the light given off by the flashlight is concentrated in one spot. If you were to hold that flashlight at an angle on the floor, the same amount of light is present but it is stretched out over a wider space. The Northern Hemisphere is tilted away from the Sun during Winter and the Southern Hemisphere is tilted towards the Sun giving them Summer. This is a straight forward article about it http://www.mountainnature.com/Climate/WhatCausesWinter.htm and you can search for diagrams of Earth's orbit to help understand it all a little bit more.
Which of these trees have wider and flater leaves?
This question cannot be answered until we know what the two trees are.
How according to the position of light source does the size of shadow differ?
It's hard to explain this in words but here goes.There are two ways a shadow changes size based on the position of the light source.If the light is just above and in front of the object the shadow is long, but as the light moves above the object the shadow gets shorter and shorter and shorter until when the light is directly above the object there is little to no shadow at all.If the light is directly in front of an object, like a person, as the light gets closer the light rays can only get past the object at a wider and wider angle (out to the sides) so the area with no light (the shadow) becomes wider and wider.
How can I purchase an LED flashlight?
Your average supermarket should sell LED flashlights. They are available and Tesco, Asda, Morrisons, Sainsburys and other shops. Specialist camping stores such as Millets will offer a wider variety.
Do convex mirrors focus light?
Convex mirrors do not focus light, but instead they diverge the light rays that hit them. This causes the reflected light rays to spread out which results in a wider field of view.
When the light is bright does the iris open to allow less light to enter?
no I can't think of a single example of anything that opens wider to allow less to enter.
Why do some plants prefer to grow in shade?
These plants have such leaves because wider, flatter leaves will catch more sunlight. Sunlight is needed for plants to survive, so when they're in the shade they adapt to be able to get more sunlight.
