If the frequency a star is shifting towards the violet end of the spectrum, the star in the above case is
1 Stationary
2 Moving away from earth
3 Moving towards the earth
4 Moving forward and backward
Explanation:
C If the frequency a star is shifting towards the violet end of the spectrum its shows apperant wave length decreases therefore source is moving towards earth.

The frequency order for $X$ - rays (A), Gamma rays (B), Ultraviolet rays (C) and Microwaves (D) is
1 B $>$ A $>$ C $>$ D
2 C $>$ A $>$ B $>$ D
3 D $>$ C $>$ A $>$ B
4 D $>$ B $>$ A $>$ C
Explanation:
A As we know higher energy of waves would have high frequency- Gamma rays $>\mathrm{x}$-rays $>$ ultra violet rays $>$ microwaves.
