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.
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.
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.
this question doesn't even make sense
All electromagnetic waves travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is a fundamental constant of nature and does not vary based on the type of electromagnetic wave.
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.
P waves and S waves. P waves arrive first and make a ripple like effect through the ground and S waves arrive second and make a twisting/circular wave.
