Human eyes can only see

UV
visible light
The bigger the wave,
the more energy it has, and the higher its amplitude.
the less energy it has,
and the lower amplitude
Sound waves are (a) that move through a medium by the vibration of particles.
When light hits a different medium (i.e. from air to water or glass)
As a sound pitch increases...
the frequency also increases
the amplitude decreases
the wavelength spreads
To double the frequency,
the wave length has to curve in a certain direction
the wavelenghth must be haved
Mechanical waves are
(a)
what are the parts of a wave?
The law of conservation of energy states that energy...
cannot be reincarnated
cannot be created nor destroyed
cannot be helpful
just read this :
Understand how light behaves when it passes through a mirror, a transparent object, and an opaque object.
what is opaque?
transparent
see throught
no transmitting lights
Light is refracted
at media boundaries.
Absorption
Media can only transmit or absorb. .....
light waves
A wave is a repeated pattern of a?
disturbance
characteristics/properties of waves
Amplitude, wavelength, frequency.
Increasing amplitude..... of a wave
Increasing energy
Increasing the frequency
increases the energy of the wave
In a spectrophotometer, the slit and the material surrounding the slit will absorb light because absorbing light is necessary feature for the slit to allow only small portion of visible light spectrum through
Prisms also transmit light
Most light is absorbed around 300 nm and the least amount of light is absorbed between 350 nm to 500 nm
visible light is between 400 and 700 nm. Ozone does not absorb light at this wavelength range and therefore light is transmitted through the ozone (this means that ozone transmits visible light to us on Earth)
UV light has a wavelength of 300 nm. Ozone absorbs most of the UV light so less UV is transmitted to Earth because it is absorbed by the ozone layer. Ozone therefore helps to protect us from sunburns because UV cannot penetrate through the atmosphere.
Prisms refract light because they...?
they bend light at an angle
