"Oh my God, look at my face through the water, dude! It's refraction of refraction!"
"Rainbows are simply the result of light refracting through moisture in the atmosphere. This is a completely different kind of rainbow, one made of fairy magic."
"When white light enters a higher index medium like glass from air, the light slows... the light will Bend or be refracted."
"Rainbows get all their different colors when sunlight shines through water, bending the light and separating it into all the colors of the rainbow."
"Refraction is the apparent change in direction of light."
"Prisms bend light towards the normal."
"Snell's law describes the relationship between the angle of incidence and refraction."
"The focal length of a lens is determined by its curvature and the index of refraction."
"The amplitude ratio is minus 1, therefore all the energy is refracted by the wall."
"The ultimate way of knowing crystal is refraction light refraction. Look for the rainbow."
"Anytime light slows down coming at an angle into a medium, the path of light bends."
"Snell's law describes the change in direction of a light ray as it moves from one medium to another."
"When light meets a denser medium, it bends towards the normal."
"Actually, the sky is blue because of light refraction and the scattering of light particles."
"When you shine white light into a prism, a rainbow comes out the other end."
"When light passes from one medium into another medium that has a different index of refraction, the light can bend."
"When waves enter areas of higher density, they tend to refract, and that's the reason why you get rainbows."
"When you hold a piece of leaded crystal up to the light and you turn it a little bit, you're gonna see tiny little rainbows within the crystal."
"The light enters the prism, bounces around, and comes out at all different odd angles, and you end up with this multicolored object which is actually really only clear."
"Refraction occurs as light goes from one medium to another and changes direction."
"The refractive index is the measure of the speed of light as it passes through a substance."
"Snell's law for refraction follows this kind of expression where u is the speed of light in the low refractive medium and v is the speed in the slower medium with the higher refractive index."
"The stars twinkling in the night sky... it's refraction."
"Refraction is the bending of light as it goes through a different medium."
"When light changes direction because it changes speeds, that's refraction."
"Refraction is basically when you're looking at something through a transparent surface, you basically see like a distorted version of whatever is behind it."
"The densities of different glass will fold the different wavelengths of light into the same focal space more correctly."
"The property of ice that we're going to be working on today is refraction."
"Dispersion happens when different wavelengths of light get refracted in a different manner."
"Now that we actually have glass that only reflects what we want and after a certain point of refraction just stops working altogether and gives us a clean result."
"Refraction is how our glasses work, and microscopes, and telescopes, and magnifiers."
"Light bends when it hits a different medium."
"If n1 is less than n2, then this ray will bend toward the normal."
"The critical angle is actually 90 minus 36."
"Refraction is a physical phenomenon which explains there is a change in the speed of light waves, sound waves, or water waves."
"The slowing down of this light inside the glass will cause it to change direction slightly, and we call this refraction."
"The refraction event is what actually causes those different wavelengths to separate."
"The reason why rainbows appear in seven different colors is because sunlight passes through water droplets in the air."
"Rainbows are observed due to the interaction of sunlight with water droplets suspended in air."
"The wavelength in solid is equal to the original wavelength divided by its refractive index."
"Refraction: the changing of direction due to a change in speed."
"The speed of light changes when light travels from one medium to another medium."
"You can adjust the index of refraction, how much it bulges the environment around it."
"The refractive index is the factor by which a wave slows down relative to a wave in outer space."
"The refractive index or the change in the speed of a wave is what's responsible for a wave bending at an interface."
"The cornea's role is to refract the light to bend that light as it enters the eye."
"When waves travel from deep water into shallow water, they bend to compensate for the change in speed."
"That, my friends, is proper refraction."
"Let's add a lot of refraction now, this is gonna pull from different parts of the background."
"It's singly refractive, so it doesn't distort light importantly."
"Chameleons actually don't change color; they just change the hue of their color by the way the light refracts on them."
"A wave in outer space, no matter what direction it's going, sees a refractive index of one."
"Critical angle is the angle of incidence when the angle of refraction is equal to 90 degrees."
"The ionosphere can refract or bend HF and VHF radio waves."
"Snell's law of refraction... the angle of incidence sine of angle of incidence to sine of angle of refraction must be some ratio of n2 to n1."
"Refraction is when a wave meets a different medium and changes direction because it changes its speed."
"The pull point of a convex lens is that it takes light from the outside and refracts it in a way so that the light converges at a point."
"Reflection and refraction are phenomena described using electromagnetic waves."
"When light is coming from a less dense medium to a more dense medium, it bends towards the normal."
