Any material object or opaque film blocks the direct transmission of light, although
there may remain some residual illumination due to diffraction around the edges of
the filter.
A polarizing pfilter blocks the transmission of light whose E-vector is not aligned
parallel to the pfilter's preferred direction.

What happens to light that passes through a horizontal polarizing filter?
Light that passes through a horizontal polarizing filter will have its electric field components aligned with the filter's direction, allowing only the component parallel to the filter to pass through. The intensity of the light will be reduced because only a fraction of the original light's intensity is able to pass through the filter.
What happens blue light passes through a blue filter?
If blue light passes through a blue filter, the light will be transmitted through the filter because the filter is designed to allow blue light to pass through while absorbing other colors of light. The blue filter selectively transmits blue light and blocks other colors of light.
What is a color of light that passes through the filter?
The color of light that passes through a filter depends on the properties of the filter. If the filter is red, only red light will pass through. If the filter is blue, only blue light will pass through, and so on.
An ideal polarizing filter transmits 50 of the incident non polarized light. Why is this so?
Unpolarized light has electromagnetic waves vibrating in all directions perpendicular to the direction of propagation. A polarizing filter only transmits light that is polarized along the same axis as the filter's axis. (Note that a polarizing filter also partially allows some orientations through that have some component of its axis along the same axis as the filter). The transmitted light thus constitutes half of the incident unpolarized light.Think of it like this: unpolarized light is like a rope vibrating up and down and a rope vibrating side to side. A polarizing filter is like "slots." If the slots are up and down, only up and down vibrations can get through. The other half- the side to side vibrations- are blocked.
What color will a red object look through a green filter?
It will look black, or green, depending on the hue of the red. A green filter blocks the red light but no red object is reflecting solely in the red wavelengths, and any non-red light will appear green through the filter.
How can two polarizing block all light passing through them?
When two polarizing blocks are aligned in the same orientation, they allow light to pass through. However, if the blocks are oriented perpendicular to each other, they block all light because the second block blocks the polarized light that passed through the first block. This is due to the orientation of the polarizing molecules within the blocks, which only allow light waves vibrating in a certain direction to pass through.
What would happen if you looked at a red light with a red filter?
A red filter blocks every color except red from getting through, so you would see red.
Are light waves caused by a vibrating object?
Light waves are not caused by vibrating objects. Light waves are electromagnetic waves that do not require a medium to propagate, unlike sound waves which are caused by vibrating objects. The vibrations of charged particles, such as electrons, generate light waves.
What happens when you look at a blue object through a red filter?
When you look at a blue object through a red filter, the object will appear darker and possibly black because the red filter blocks out most of the blue light. The red filter only allows red light to pass through, which results in absorbed blue light and altered color perception.
Why ll a light fitted with both blue and green filters appear black?
The blue filter allows only blue light to pass and blocks red and green light. The green filter allows only green light to pass and blocks red and blue light. Therefore, the two filters together block all light.
What colour is red light if you look at it through a blue filter?
You can't see it because a blue filter only lets blue light in, and red is made up of just red light, no blue, so none passes through (or it gets reflected, can't remember which)
What type of energy is vibrating light?
Electromagnetic Energy.
