If light is a wave why can't you see it if you are at right angles to it's movement?
You mean that we shouldn't be able to see the light if we stand at right angle to its movement? Well, this happens with laser rays. For the non-laser light it does not happen for two reasons. First, if the source of light emits light all over the space, and you are in that space, then there is no room for you to stand in order to be at right angle to its movement. Second, even if the source of light does not emit light all over the space, and you stand at right angle to its movement, the light scatters in the air, and it comes into our eyes.
What else can I help you with?
Why and how do shadows change?
Shadows change due to the movement of the light source or the object blocking the light. As the position of either the object or the light source shifts, the size, shape, and direction of the shadow will also change. This change occurs because shadows are created when an object blocks light, so any alterations in the light source or object will impact the resulting shadow.
What is a material that light can't travel through?
There is no known material that light cannot travel through. However, materials such as lead and thick concrete can significantly attenuate or absorb light, making them almost opaque to visible light.
What do you call it when light cant go through it?
An object that does not allow light to pass through it is called opaque. Opaque objects absorb or reflect light, preventing it from transmitting through them.
What can light travel through that sound cant travel through?
Light can travel through a vacuum, such as outer space, where sound cannot travel as it requires a medium like air, water, or a solid to propagate. Light can also travel through transparent materials like glass or air, while sound is mostly blocked or absorbed by these materials.
What types of light humans cant see?
Ultraviolet light and infrared light are two types of light that humans cannot see. Ultraviolet light has shorter wavelengths than visible light, while infrared light has longer wavelengths. Both types of light are beyond the visible spectrum for humans but can be detected with specialized equipment.
Why cant a rectangle be a trapezoid?
A rectangle has four right angles; a trapezoid doesn't.
How do you draw a pentagon with four right angles?
you cant because it would be a square
Your lengths cant be measured when 2 of us meet you form right angles?
It is perpendicular lines
Why cant a right triangle be an equilateral?
An equilateral triangle can't be a right triangle since an equilateral triangle has all 60° angles, which are NOT right angles [measuring 90°]. If a triangle is a right triangle, then it has a right angle!
Why cant a quadrilateral have exactly 3 right angles?
A quadrilateral can only have either 2 right angles or four. As you may (or may not) know, the angles in a quadrilateral must add up to 360 degrees. If you have 3 right angles that adds up to 270 degrees, so the last side must also be 90 degrees.
Can a trapezoid be drawn with 3 right angle?
a trapezoid has no right angles whatsoever. no they cant because trapezoids have only 4 sides and dented
How is geomerty used in the real world?
without geometry, we cant build a house in a right manner because, we need to now the angles and the right measurements....
When all angle in a triangle measure axactly 90 degrees?
It cant be possible because a triangle only consists of 180 degree angles !! As 90 + 90 = 180 thus 2 or more than 2 angles in a triangle cant be right angles i.e. 90 degree :D
Why cant there be a obtuse angle in a right triagle?
A triangles angles must add up to 180 degrees, no more or less
Why cant an equilateral triangle have a right angle?
eqilateral triangle has 3 equal angles.by asp , sum of angles is 180, thus, angles are 180/3=60 degree each
Which can never be true for supplementary angles?
They cant be what their not.
Who is crooks and why cant he play cards with the other workers?
Because he african american! and the civil right movement wasn't there yet!
