A torch emits light from the bulb. A mirror gives off light by reflection.
There are two ways that the color white occurs, as light and as the color of an object. When you see white light it is a combination of many colors of light, because white light is a combination of all light. When you see a white object, that object is reflecting all of the colors of light back at you, because that surface doesn't absorb any of the colors of light.
The two ways to measure the density of an object are by using its mass and volume. You can calculate density by dividing the object's mass by its volume, or by measuring the displacement of water when the object is submerged in it.
back and forth?
When there is two light soucres near the object
There are probably thousands of ways to answer this question. 1. You can push an object. 2. You can throw an object. When the object collides with another object, the collision will produce force.
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.
U can increase and decrease it
An object can form two or more shadows at a time if there are multiple light sources casting light on it from different directions. Each light source will create its own shadow of the object, leading to multiple shadows being formed.
When light strikes an object, it can be absorbed by the object, converting into other forms of energy, or it can be reflected off the object's surface, allowing us to see the object if the reflected light reaches our eyes.
When the speed of light in the two media is not the same.
The acceleration of an object can be increased by either increasing the force acting on the object or by decreasing the mass of the object.
Decrease the mass, and change the force.
