Light
What is reflection?
When light passes through off something like a mirror instead of passing through.
What is sound
Sound is a longitudinal wave that can only travel through matter.
What is wavelength?
wavelength is the distance between identical points of consecutive waves
What part of the eye is the transparent outer layer that helps focus light entering the eye.
What is transmittance?
Transmittance is the way to measure how much light goes through something.
What is pitch
The pitch relies on frequency. High frequency equal high pitch.
What is frequency
Frequency refers to the amount of vibrations or cycles, that sound waves completes per second.
What part of the eye adjusts the size of the pupil to control the amount of light that enters.
Iris
What is a diffuse reflection?
It is a reflection that occurs from a rough surface and doesn't form a clear image. eg sandpaper
What does sound travel in the fastest?
Solids
What is period?
The time it takes to complete a full cycle of a sound wave to pass through a certain point.
What is the light-sensitive layer at the back of the eye contains rods and cones, which detect light and send signals to the brain.
Retina
Refraction is the bending of light as it passes from one thing to another.
What is a compression?
A compression is a region where molecules are closer together
What is the speed of the wave if the wave has a wavelength of 12.0 m and a frequency of 20.0?
240
What part of the eye controls the amount of light entering by changing the size of the opening in the center of the iris.
pupil
How does a one-way mirror work
A one-way mirror it's reflective on one side and allows light to pass through on the other side.
What is a rarefaction
A rarefaction is a region where molecules move farther apart
What is the frequency, if the wave has a wavelength of 0.5 m and a speed of 80 m/s?
160
How is the image that is formed on the retina of human eye?
Virtual and inverted.
