What is the speed of an electromagnetic wave with a frequency of 5.21 1016 Hz and a wavelength of 5.76 nm?
The speed is equal to the product of the frequency and the wavelength. First convert the wavelength to meters, so as to have compatible units.The speed of an electromagnetic wave in a vacuum is ALWAYS the same - around 300 million meters/second. If you get any result, something is wrong - unless the wave travels through some other medium, in which case its speed can be less than the speed of light in a vacuum.
If you have a strong infrared absorbance at 1500 cm-1. what is the wavelength of its frequency?
1501
Does water vapor condense when it travels far above earth?
Yes it does. It is part of the hydro logical cycle.
Why is the wavelength of light multiplied by the frequency of light is equal to the speed of light?
v=fλ (velocity (m/s)=frequency (s^-1) * wavelength (m)When dealing with light v=hf is also useful (same derivation as for above), where h is the Planck constant.
In an experiment the hypothesis is If the wavelength of the light shining on a plant is shortened the rate of photosynthesis is slowed down If this experiment is performed?
a) testiable b) falisable c)both of the above d) none of the above the answer is , B ; falsiable . (: ENJOYYY ! <3
How do you prove that speed equals wavelength times frequency?
Frequency is the number of waves per second, i.e. 20Hz is 20 waves per second. Wavelength is obviously the length of each wave i.e 20m So if there are 20 waves per second, the distance it travels is the length of the wave multiplied by the number of waves in one second. The distance travelled in one second by the wave above is therefore 20 * 20m wich is 400m. The distance travelled in 1 second is 400m. Therefore every second, the wave travels 400m and thus the speed is 400meters per second (400m/s).
What makes a mountain a mountain instead of a hill?
The general distinction between a mountain and a hill is based on their height and steepness. Mountains are typically taller, have more significant elevation changes compared to their surroundings, and often have rugged terrain. Hills are smaller landforms that are not as tall or steep as mountains.
Use the definition of the meter to determine how far light travels in 1 ns?
Light travels 3/10 of a meter in 1ns or light travels 1 foot in 1ns. The answer above is clearly wrong, light travels so fast that you cannot time it with a stopwatch etc. Light travels at 300,000 kilometres a second. One millisecond is one thoudandth of a second. One metre is one thuosandthy of a kilometre. Thus in one thousandth of a second, light travels 300,000 metres. Please, somebody, check my logic! Your logic is right but your numbers are not. 1 ns means one nanosecond , a billionth of a second ,not a millisecond. I do wish people would write out words in full, and not rely on someone interpteting an abbreviation correctly. E.G. 'm' as a unit of length, which I have seen refering to 'miles' or 'metres'! It's so easy in a complex question, e.g. about the speed of light, to mistake one unit for another if just the initial is used. Thanks for the correction above.
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.

How do you calculate wavelength of a sound wave?
v = fλ V/f = λ (wavelength) V = 340ms-1 340/f = λ In short you need to know the frequency of the particular sound wave to work out it's wavelength. once you know that you plug it into the above equation and you will get the wavelength of the wave.
When light travels 1.86X10 to the fifth power miles in 1 second how far does light travel in one year explain your answer?
light travels one light year in one years timeokay so whoever wrote this above is a retard, and light travels 6 trillion miles in one year, there is 525,600 minutes in a year, times that by 60, then do your 1.86X10 to the fifth and there you go
Is the word above a first or second accented syllable?
Above is accented on the second syllable.
What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?
Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules
Is above on the first or second syllable?
Second syllable.
Is above a first or second accent syllable?
Above is a second accent syllable.
