separated by a distance of 1.25 mm. An interference pattern is
formed on a screen a distance 3.3 m away.
What is the distance between the 9th bright spot
and the centre of the pattern?
Please enter your answer
in cm to two
decimal places but do not enter units in your
answer.
- Light With A Wavelength Of 650nm Is Incident On Two Slits Separated By A Distance Of 1 25 Mm An Interference Pattern Is 1 (32.37 KiB) Viewed 17 times
function of 4.7 eV is used.
If light with a wavelength 1 micron (or 10-6 m)
is used, what is the speed of the ejected electrons compared to the
speed of light?
Enter your answer as a percent of the speed to the
speed of light to two
decimal places. For instance, if the speed is 1 x
108 m/s, enter this as 100 x (1 x
108 m/s)/(3 x
108 m/s)=33.33.
- Light With A Wavelength Of 650nm Is Incident On Two Slits Separated By A Distance Of 1 25 Mm An Interference Pattern Is 2 (37.53 KiB) Viewed 17 times
wavelength of the electron?
Enter your answer
in nm to two
decimal places but do not enter the units
- Light With A Wavelength Of 650nm Is Incident On Two Slits Separated By A Distance Of 1 25 Mm An Interference Pattern Is 3 (15.96 KiB) Viewed 17 times
slit which has a width of 0.1 microns (10-6 m).
What is the angle at which the first diffraction minimum is
found?
Enter your answer
in radians to four
decimal places but do not enter the units.
If you could not determine the wavelength of the electron in the
previous question, you may use a wavelength of 1 nm.
- Light With A Wavelength Of 650nm Is Incident On Two Slits Separated By A Distance Of 1 25 Mm An Interference Pattern Is 4 (33.76 KiB) Viewed 17 times
In a photoelectric effect experiment, a metal with a work function of 4.7 eV is used. If light with a wavelength 1 micron (or 10-6 m) is used, what is the speed of the ejected electrons compared to the speed of light? Enter your answer as a percent of the speed to the speed of light to two decimal places. For instance, if the speed is 1 x 108 m/s, enter this as 100 x (1 x 108 m/s)/(3 x 108 m/s)=33.33.
An electron has a kinetic energy of 4.2 eV. What is the wavelength of the electron? Enter your answer in nm to two decimal places but do not enter the units
An electron has an energy of 4.2 eV. It is incident on a single slit which has a width of 0.1 microns (106 m). What is the angle at which the first diffraction minimum is found? Enter your answer in radians to four decimal places but do not enter the units. If you could not determine the wavelength of the electron in the previous question, you may use a wavelength of 1 nm.
