Why is it possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre?
There are a few reasons why it is possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre. One reason is that when light passes through a lens, the lens refracts the light in such a way that the light is brought to a focus. The amount of refraction that occurs depends on the curvature of the lens and the index of refraction of the lens material. However, no matter how curved the lens is, the amount of refraction is always the same at the optical centre of the lens. This is because the optical centre is the point on the lens where the light rays passing through the lens are parallel to the principal axis of the lens. Another reason why it is possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre is that when a lens is rotated about its optical axis, the image formed by the lens does not rotate. This is because the optical centre of a lens is invariant with respect to rotation. This means that it is not necessary to take into account the actual refractions that occur at different points on the lens when calculating the image formation by the lens.
Why does diffraction not occur when light passes through a window?
The window is too wide (relative to the wavelength of light)
Does dispersion occur through a hollow prism?
No, dispersion doesn't occur through a hollow prism.
Monochromatic light passes through 2 parallel slits forms an interference pattern on screen As the distance between the 2 slits is decreased the distance between light bands in the pattern?
The light will be diffracted and an interference pattern of alternate dark and light areas will occur on the wall.
How does radiation occur in a light bulb?
Yes, if its on.

Does refraction occur when light passes through a piece of glass?
Yes, it is true.
Can light travel through prisms?
Yes light can travel through prisms. At some points it would occur total internal reflection and at some points there would be refraction of light.
Why do pop and spray not occur at the same time?
Light and sound travel through the air.
Why does diffraction not occur when light passes through a window?
The window is too wide (relative to the wavelength of light)
What is the difference between the light dependent reactions and the light independent reactions?
light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark
What Will Most Likely Happen To a Plant That Does Not Does Not Receive Any Water?
The light-dependent reactions will not occur.
What has to occur for us to see color?
colour must occur in one of three ways: light must be refracted off a surface. light must pass through a fliter or prism or liquid. light must be projected. Of the correct wavelength to produce a colour. the light must then pass into the back of the eye and hit the rods and cones at the back of the eye. Then the brain must process the image through the optic nerve.
What is primary source of light?
The primary source of light on Earth is the Sun. It emits light and heat energy through a process called nuclear fusion in its core. This light sustains life on our planet and allows for photosynthesis to occur in plants.
Where does light dependent occur in the chloroplast?
Light- independent reactions of photosynthesis occur in the stroma of the chloroplasts of a cell.
What is the difference between light-dependent reactions and light-independent?
light dependent reactions only occur in light this means thier reations increases with light intensity while light independent can occur in the dark
Does dispersion occur through a hollow prism?
No, dispersion doesn't occur through a hollow prism.
