The type of energy transferred by a wave in a medium is energy
What is the reciprocal of frequency
The reciprocal of frequency is the time period of the wave
When sound waves interfere to create standing waves the points on the medium that move up and down with the largest amplitudes are called nodes
Photons with the highest energy have the longest period
False
they have the shortest wavelength (period)
On the decibel scale an increase of decibels means an intensity increase ten times
When a wave moves from a dense medium to a less dense medium most of the wave energy is
The pitch of a sound is determined by its and speed together or its frequency alone
The pitch of a sound can be determined by its frequency
alone.
The amount of diffraction that occurs when a sound wave encounters a barrier depends on the waves
Length of a lens is the distance from the center of the lens to its principal focus
All electromagnetic radiation are
The primary colors of visible light are red orange yellow green blue and violet
The primary colors of visible light are red blue and what
What is a sort of device is commonly used to separate the colors of light from white light
A prism is the right answer
Can you able to see all of the forces that affect an object
no,we can not see all the forces that affect an object.
We are able to see an object when it emits or reflects one or more visible light frequencies
At the point of a converging lens the object cannot be seen.
What All of the visible color light waves together result in light
A diverging lens only produces a virtual image because the light rays never:
