Light travels in straight lines until it hits a prism, where it bends and spreads out into different colors. This bending, called refraction, happens when light moves from one transparent medium to another. Depending on the frequency of the wave, it could refract more or less.

- 2. It means it hits an angle of the glass triangle.
- Sound can't pass through vacuum beacause it needs air but there is no air vacuum so sound waves can't pass i hope you understood a little bit of so...
- space is a vacuum because it has practically no atoms
- Refraction is the redirection of a wave as it passes from one medium to another. It can be caused by the wave’s change in speed or by a change in t...
- Yes, light can travel through many mediums. We often talk about the speed of light through a vacuum because that speed is constant. In our everyday...
In the next video, we're going to talk about a lot of the properties of a periodic wave. How the wavelength, and its frequency, and its period relate to its velocity, and all of that. But I'll leave that alone in this video.

- Andrew M's answer is definitely correct if you meant sound through an electrical speaker; however, if you are referring to a tin can telephone, the...
- To elaborate a bit, building materials are transparent to long wavelength waves because a wall will only absorb the energy of waves that have the r...
- It's actually quite hard to define energy, but I would say @Ethan Dlugie gives the best definition here.
- Light can exert pressure though not much. The pressure exerted by electromagnetic radiation is called *Radiation Pressure*. http://en.wikipedia.org...
- yes they make the tiniest amount of sound,according to the no of vibrations,called hertz,the sound is inaudible below 20hz
- In microwaves, electromagnetic waves are used to heat up your food. The waves in your microwave are the same sort of waves that make up visible light.
- Great question! Unfortunately, the answer is kind of complicated. In general, if you keep EVERYTHING ELSE the same, the speed of sound in a gas (li...
- Some molecules which are pushed forward collide with the particles which are already present in the space forward. Because of these collisions they...
- Transverse waves: Electromagnetic waves(light waves, Radio waves),wave in a string etc. Longitudinal waves: compression waves in a spring, sound wa...
- Yep! Even the most tiniest amount of sound is made by the vibration of atoms, just like any other.
I understand that amplitude determines volume and frequency determines pitch. What changes the quality of a sound? For example, an oboe, a violin, and the speaker in this video can all produce a sustained 440 hz A at the same volume. Why do they sound different?
