(frequency) = (speed) / (wavelength) = (15 m per sec) / (3 m) = 5 per sec = 5 Hz.
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
The period is ' 1 ' divided by the frequency. (The reciprocal of the frequency.)The question tells us the frequency . . . "3 per second".So the period is 1/3rd of a second .Having the frequency, the wavelength doesn't give us any more information (except thatnow we know the speed of the wave, but that's irrelevant at the moment.)
period and frequency are reciprocals period (T) = 1/frequency (1/f) period = 1/18
A vector quantity is a physical quantity having magnitude and direction both. For e.g. velocity is a vector quantity and in physics it is velocity is generally denoted as: v (bar) = 2i+3j+4k where in general, i=velocity in x-direction j=velocity in y-direction k=velocity in z-direction 2,3 and 4 are magnitudes respective to their directions.
Certainly. For example, a pendulum at its left-most position.
The speed of a wave = (frequency) x (wavelength) = 2.5 meters per second.
Wavelength = Velocity / FrequencyTherefore:Frequency = Velocity / WavelengthVelocity = c, the speed of light, which is 299,792,458m/s.We know the wavelength is 413nm, which is 4.13*10-7m, so our equation is:f = (3.00 * 108) / (4.13 * 10-7) = 7.259 * 1014Hz
Each colour has different wavelengths....For example: In VIBGYOR It is in the order of increasing wavelength i.e Compared to red violet is having the shorter wavelength..... The frequency and wavelength are related by the equation: In vaccum: frequency= c/wavelengthwherec is the velocity of light in free spaceWhereas in any medium,frequency= Velocity of light in that medium/wavelength So, it is clear from the formula that the wavelength and frequency are inversely proportional to each other.... As the wavelength changes with colour the frequency also changes according to that.............. If the frequency is high, the wavelength will be low and viceversa....
Each color has a different frequency and wavelength; with red having the longest wavelength and lowest frequency of all the visible colors & violet having the shortest wavelength and highest frequency of the colors humans can see.
For any wave, the speed of the wave is the product of its frequency and of its wavelength.
Because red light has minimum frequency and thus it has maximum wavelength.
At a single wavelength, it is called monochromatic
They are both transverse waves, albeit having different wavelength and frequency. I think that velocity of the waves will also be different as x-rays travel at the speed of light.
The speed of any wave =Frequency *Wavelength here, frequency =1.49*1017 Hz & wavelength=6.39 nm =6.39* 10-9 m So speed=9.52*108 m/s
Gamma rays are the waves with the shortest wavelength. The waves having highest frequency have the shortest wavelength. As gamma rays have the highest frequency starting from 10^19 and onwards so they have the shortest wavelength starting from 10^-11 and decreasing.
Visible light has the spectrum VIBGYOR. Violet is at one extreme having highest frequency and red is at the other end having least frequency. Less frequency means having longest wavelength, since wavelength and frequency are inversely related. As we go beyond violet then it is named as ultraviolet. Same way as we go beyond red, then it known as infra red. So its wavelength has to be greater than that of red. Hence longer wavelength for IR radiations. IR is what we call 'thermal' radiation, in other words, 'heat'.
