Speed of light = 299,792,458 meter per second = 29,979,245,800 cm per second
Wave Length = λ = 4 x 10-5 cm = 4 / 100000 cm.
So no of waves passing a point per second = 29,979,245,800 x 100000 / 4
= 749,481,145,000,000 = 74,948 billion waves per second
turn the light on
The waves get wider and dimmer as they move.
by radiation waves
Nope
it sure is!!yes, light waves is a transverse wave.
Sound is something you hear. It is a vibration which travels in waves and then hits your eardrum to make it vibrate, that's how you hear it. It is the second fastest thing, first is light.
These are the main electromagnetic waves we can see. We see these waves as the rainbow's shades. Every shading has an alternate wavelength. Red has the longest wavelength and violet has the briefest wavelength. At the point when every one of the waves are seen together, they make white light. At the point when white light radiates through a crystal, the white light is broken separated into the shades of the noticeable light range. Water vapor in the air can likewise break separated wavelengths making a rainbow.
All visible color light waves together make up white light. White light is a combination of all the colors in the visible spectrum, which can be seen when light is dispersed through a prism.
They all travel the same speed in space. Which travel the farthest in the same amount of time are microwaves. Think of it this way...walk to the park in the city 8 blocks away by moving from one side of the sidewalk to the other. - or - walk down one block, make a left, walk one block make a right, walk one block make a right, walk two blocks make a left, walk one block make a left, walk two blocks make a right...etc You walked the same speed for both....you got to the park faster by just side to side on the same sidewalk
this question doesn't even make sense
Laser light is made up of coherent and monochromatic light waves. Coherent means that all the light waves are in phase with each other, and monochromatic means that the light consists of a single color or wavelength. This allows laser light to be focused into a tight beam with high intensity and precision.
The frequency of the wave passing through the rope would be 1 hertz, as one wave passes every second. Frequency is measured in hertz, which represents the number of waves passing a certain point per second.
