Answer:
550 nm
Explanation:
The formula for the double-slit diffraction experiment is:
where
y is the distance of the m-th maximum from the central fringe
is the wavelength of the light used
D is the distance of the screen from the slits
d is the separation between the slits
In this problem we have:
is the distance between the slits
is the distance of the screen
We also know that the distance between the 3rd and 5th order maximum is 5.5 mm, which means that:
And we can rewrite this as:
where we used respectively m=3 and m=5. If we know solve for , we find the wavelength:
Cardiovascular exercise involves movement that gets your heart rate up to improve oxygen consumption in the body.
Examples of cardiovascular exercise (Aerobic) include:
Spinning
Running
Swimming
Walking
Hiking
Dancing
Kick Boxing
Answer:
photosynthesis is the process by which green plant manufacture their own food using sunlight from the sun , water and mineral salt from the soil
Answer:
At the molecular level, materials are held together by bonds, which act like springs for small displacements from the equilibrium spacing between neighboring atoms. Push the atoms close, the bond pushes back to keep them apart. Pull them apart, the bond pulls the atoms closer. For those small displacements, it acts like a spring
The speed of the wave will be related to the stiffness of of those springs - you compress the material - how quickly do all of those little springs rebound and push their neighboring atoms away, sending that wave of compression through the material.
Explanation:
Answer:
18 miles
Explanation:
The average speed is 6 mph
Melanie ran for 3 hours
Speed × Time = Distance
So, 6 mph × 3 h = 18 miles
