The strongness of a sound describesits loudness in ~ a particular distance
The pitch of a sound is most very closely related to thefrequency that vibrations
Resonance describes an impact in i beg your pardon thevibration of one thing causes an additional object come vibrate at herbal frequencies
A sonar system steps distance by identify thetime that takes because that sound waves to bounce turn off a surface
A sonar system actions distance by identify thetime the takes because that sound tide to bounce off a surface
An ultrasound device can create images of human body structures due to the fact that of soundwavestravel at different speeds through products of various densities
The particle version of light defines how irradiate cantravel without a medium
The quantity of energy in a photon of light is proportional to thefrequency the the matching light wave
The price at i m sorry light energy flows through a given area of room is referred to as itsintensity
When irradiate rays reflect off a rough surface, theyscatter in plenty of different directions
The law of reflection states that when light beam reflect turn off a surface the edge of incidenceequals the angle of reflection
An photo that outcomes from an noticeable path of light rays is calleda online image
An orange looks orange because itreflects orange light and absorbs other colors
You look at a red tulip with eco-friendly leaves under environment-friendly light, what would you see?a black flower with eco-friendly leaves
the color that an item appears come be depends on thewavelengths the light that the thing reflects
When light moves native a product in i beg your pardon its rate is higher to a product in i beg your pardon its speed it greater to a product in i m sorry its speed it slower, that isbent away from normal
A virtual picture caused by enjoy of light in the atmosphere is called...a mirror
Light that enters one finish of a fiber optic cable reaches the other end by method of...
