Fiber bragg gratings a fiber bragg grating is written in a fiber (n=1.5) with a strength = 2em and length = 2 cm at 2=1550nm. a) what is the bandwidth of the grating in nm? b) what is the reflectivity (in %) and transmission (in db)? c) if this grating were written in birefringent fiber where the difference in refractive index for the two polarizations, an = 10, what is the separation in grating wavelengths for the two polarizations? d) will this grating be any good for filtering unpolarized light?

momentum of soft ball three times less than baskey ball

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
