Answer:
and 
and 
Explanation:
= Wavelength
= Angle
m = Order
Distance between grating is given by


We have the relation

m = 1

m = 2

The first and second order angular deflection is
and 

m = 1

m = 2

The first and second order angular deflection is
and
.
Please give us the picture and tell us what quantity you're asked to find.
Answer:
95 minutes
Explanation:
According to N.A.S.A, the Hubble Space Telescope makes one orbit around Earth every 95 minutes.
"The Hubble Space Telescope is a large telescope in space. It was launched into orbit by space shuttle Discovery on April 24, 1990. Hubble orbits about 547 kilometers (340 miles) above Earth. It is the length of a large school bus and weighs as much as two adult elephants. Hubble travels about 5 miles per second: That is like traveling from the eastern coast of the United States to the western coast in 10 minutes. Hubble is solar-powered.
Hubble takes sharp pictures of objects in the sky such as planets, stars and galaxies. Hubble has made more than one million observations. These include detailed pictures of the birth and death of stars, galaxies billions of light years away, and comet pieces crashing into Jupiter's atmosphere.
Scientists have learned a lot about the universe from these pictures. Many of them are beautiful to look at."
In a solid particles vibrate back and forth
Answer:
Gamma radiation
Explanation:
There are three types of ionizing radiation:
- Alpha radiation: it consists of alpha particles, which are nuclei of helium (so, they contain 2 protons and 2 neutron) --> therefore, they have a net charge of +2 (given by the positive charge of the two electrons)
- Beta radiation: it consists of electron (in case of beta-minus radiation) or positrons (in case of beta-plus radiation). Therefore, in both cases the radiation is electrically charged: charge -e for the electrons, charge +e for the positrons
- Gamma radiation: it consists of high-energy photons. Since photons are electrically neutral, gamma radiation has no electric charge associated with it.
