Refraction occurs when light travels from one medium to another with a different optical density, causing the light rays to change direction. This change in direction is due to a change in the speed of light as it moves through the different mediums. The amount of refraction that occurs depends on the angle at which the light enters the new medium.
What else can I help you with?
If you place a charge into an electric field it will move in the direction indicated by the electric field lines?
Yes, a charge placed in an electric field will experience a force and move in the direction of the electric field lines if it is positive, or opposite to the direction if the charge is negative. The force on the charge is proportional to the charge itself and the strength of the electric field at that location.
In single slit if width of slit increased what will happen?
if the width of one slit is increased relative to the other the slit separation must decrease and since slit sep is inversely proportional to fringeseparationthe fringes become closer together.
How do refraction and diffraction differ?
diffraction is a phenomenon in which a ray of light bents through sharp edges whose dimension is comparable to the wavelength of light...whereas in scattering a mixture of lights splits up into its component colours with help of refraction.
Why do you need to measure very small interval of time?
We need to measure incredibly small time periods because the standard hours, minutes, and seconds don't always suffice. If you want to learn more in your science projects refer to SB Components you can learn amazing things here.
Why does the refraction happen?
Refraction happens when a wave enters another medium at an angle. The wave direction will bend towards the normal (an imaginary line perpendicular to where the two media meet) if the medium it is entering is denser and will bend away from the normal if the medium is less dense. The density of the media directly correlates to their speed. As you probably guessed, the denser the medium the slower it is. So basically when the wave bends toward the normal because it's entering a denser medium, it does so because the medium is slower. An example that I heard from my physics teacher and find really helpful is what I've dubbed the Lawn Mower Analogy. Basically, think of mowing a lawn (slow/dense medium) with your lawn mower (ray). So you're going at an angle and all of a sudden you hit the sidewalk (fast/shallow medium). The first wheel that hits the sidewalk starts veering faster but the other wheel's still stuck on the grass, so it starts turning towards the border (away from the normal). When both wheels are on the pavement, the angle between lawnmower now is larger than when it was on the grass.
