Does light travel faster through air or through lens?
Air.
Which color of light travels fastest through a telescope lens?
All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
Do lenses refract light?
when light falls from air on lens it undergoes refraction as lens is denser than air light on entering lens move towards normal and is bent and while leaving moves away from normal
Do all light waves that travel through a convex lens always pass through the focal point?
No, not all light waves that travel through a convex lens pass through the focal point. It depends on the wavelength of the light, since light of different wavelengths diffract at different angles when encountering a change in media, such as air to glass, at an angle. Isaac Newton noted this in his study of light and prisms.
How light will travel from medium air to silver?
Light will not travel into silver.
Can light wave travel through air?
Yes, light waves can travel through air because air is a medium through which electromagnetic waves can propagate. Light travels at different speeds through different mediums, but it can definitely travel through air.
Can light travel through air?
yes. if light didn't travel through air, then you wouldn't be able to see anything!
How do light rays travel to your eye from a lighted candle?
Light rays travel in straight lines from a light source, like a candle, and pass through the air until they reach your eye. Once the light rays enter your eye, they are focused by the lens onto the retina, where they stimulate the nerve cells to create an image.
Why is it necessary to use emmersion oil with the 100x objective?
because at this magnification the light diffraction in air is to important to have enough light reach the lens, so oil should be in the contact between the slide and the lens because it has a much lower refraction index than air allowing more light to reach the lens
Can light waves travel better in water or air?
Since air has a lower optical density than water, light waves can travel faster in air.
What part focuses light?
A parabolic mirror best focuses light onto a spot. Or a convex lens will do similar. In the eye, the lens towards the front of the eye focuses light onto the retina, where the light sensitive cells lie.
How does the light travel in the air?
As an electromagnetic wave.
