Why should slit width be approximately equal to wavelength of light for diffraction?
This is to maximize the effect of diffraction. The wavelength of the photon can be regarded as its 'size' . If it is too large then the slit is just to small for it and most of the photons will be absorbed or reflected. If it is far too small then the slit, in comparison, will be very large so most photons do not even notice its presence and will just continue on their merry way without interacting with it.

A thin layer of oil with index of refraction 1.28 is floating on water what is the minimum thickness of the oil in the region that reflects green light of wavelength 536 nm?
The minimum thickness of the oil film should be equal to half the wavelength of light in the oil medium (because of phase change upon reflection). The formula for minimum thickness is: t = λ / (2 * n), where t is the thickness, λ is the wavelength of light, and n is the refractive index of the medium. Plugging in the values, we get t = 536 nm / (2 * 1.28) ≈ 209.4 nm. So, the minimum thickness of the oil film should be approximately 209.4 nm.

What is the formula relating speed of light frequency and wavelength?
the speed of light equals the frequency multiplied by the wavelength.
How are frequency speed and wavelength related?
Frequency, speed, and wavelength are related through the formula: speed = frequency x wavelength. This means that as frequency increases, wavelength decreases to maintain a constant speed, and vice versa. This relationship is described by the wave equation, where the product of frequency and wavelength determines the speed at which a wave travels.
Two liters is equal to approximately?
Two liters is equal to approximately 67.63 fluid ounces.
When does maximum diffraction occur?
Maximum diffraction occurs when the size of the diffracting opening or obstacle is comparable in size to the wavelength of the wave passing through it. This condition allows for the most bending or spreading of the wave, resulting in a more pronounced diffraction pattern.
When does diffraction occur?
When gap size is equal to wavelength
What is the frequency of 780 NM?
Frequency is equal to constant divided by wavelength. 3.00x108 / 780nm equals approximately 4397435897.4359 hertz.
What will happen if the width of clear space and ruled space is made equal in diffraction grating?
If the width of the clear space and ruled space in a diffraction grating is made equal, it will result in the zeroth order of diffraction being suppressed. This is because the light will predominantly be diffracted into higher orders due to the equal spacing of the slits, leading to changes in the overall diffraction pattern observed.
If you wished to produce a sound with a wavelength in air equal to the length of the room 5 meter what would be its frequency?
To calculate the frequency, you can use the formula: frequency = speed of sound / wavelength. The speed of sound in air is approximately 343 meters per second. Since the wavelength is equal to the length of the room (5 meters), the frequency would be 343 / 5 = 68.6 Hz.
What is the wavelength of an electromagnetic wave that has a frequency of 3 MHz?
An electromagnetic wave has a velocity "c", the universal wave equation velocity = wavelength * frequencythe wavelength then equal c / frequencythen the wavelength of that wave is : Lambda= c / Nu= 299792458 / 3*1000000 = 99.930819333333333333333333333333 meters ~ 100 meters(Lambda is the wavelength, Nu is the frequency).====================================To summarize:Wavelength = (speed) / (frequency) = (3 x 108) / (3 x 106) = 102 = 100 meters, in vacuum
What is the frequency of a UV photon at 350nm?
The frequency of a UV photon with a wavelength of 350 nm can be calculated using the equation: frequency = speed of light / wavelength. The speed of light is approximately 3.00 x 10^8 m/s. Plugging in the values, we find that the frequency of a UV photon with a wavelength of 350 nm is approximately 8.57 x 10^14 Hz.
What is the principle difference between radio waves and visible light?
Both of these are part of the electromagnetic spectrum. The main difference between the two is the wavelength and frequency. (Frequency multiplied by Wavelength always equals the Speed of Light, the constant abbreviated as "c". This is approximately equal to 186,000 miles per second or 300,000 km per second. If you know the wavelength and you want to find the frequency, divide "c" by the wavelength. )
What is the relationship between the frequency and wavelength of electromagnetic waves?
The product of (wavelength) times (frequency) is equal to the speed of the wave.
How is wavelength related to frequency for waves moving at a constant speed?
Wavelength and frequency are inversely proportional for waves moving at a constant speed. This means that as the wavelength increases, the frequency decreases, and vice versa. The product of wavelength and frequency is always equal to the speed of the wave.
What is wavelength of 40 hertz?
The wavelength of a 40 Hz wave can be calculated using the formula: wavelength = speed of sound / frequency. For example, for sound traveling at 343 m/s (speed of sound in air at room temperature) a 40 Hz wave would have a wavelength of approximately 8.6 meters.
Wave speed is equal to multipied by frequency?
The speed of a wave is equal to the product of its frequency and wavelength.
