Sound and Light

Name: Jaimie Durler Logan SerketichSound And Light

Light travels in straight lines unless reflected or refracted

The light ray in this picture is traveling straight until it hits a different material and is reflected on to the white screen.

Visible light is one component of the electromagnetic spectrum

Light can be reflected with mirrorsIn this picture, it shows the light hitting the two mirrors and is being reflected.As it moves, the light moves to different angles.

Light can be refracted with lensesThe lens in the picture is bending the light rays that travels through it.Refraction makes straight objects in water look bent.

Light is essential for visionThe light from a light bulb hits the duck and bounces off the surface of it into the human eye.

Sound travels through solids, faster than gases.And is louder when traveling through matter than gases.

Sound is affected by the matter through which it travels

Description of how sound waves travelSound waves travel in all directions.They get bigger the farther they travel.They travel 331 m/s at 0 degrees Celsius and 20 degrees Celsius it travels 343 m/s per secondSound travels faster through solids.

Sound waves have length, frequency, and amplitudeWavelengthFrequencyAmplitude
