1 answer:

5 0

Answer:

Energy is released. In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy.

g The first step in the process is to calibrate the grating, so we know the grating spacing (the distance between the openings i

Trava [24]

Answer:

The grating spacing is $d = 1055nm$

Explanation:

From the question we are told that

The wavelength is $\lambda = 590 nm = 590 *10^{-9}m$

The angle is $\theta = 34^0$

The order of the spectrum is $n = 1$

Generally in grating grating the condition for maxima to occur is

$d sin \theta = n \lambda$

where d is the grating spacing

making d the subject of the formula

$d = \frac{\lambda }{sin \theta }$

Substituting values

$d = \frac{590 * 10^{-9}}{sin (34)}$

$d = 1055nm$
