Question

Fill in the blank by suitable conversion of units -
1 m = ___ LY

Answer 1

TO FIND

1 m = ___ Light Years

SOLUTION

We know,

$\boxed{\bf{Distance=Speed \times Time}}$

Speed of light = 3 × 10⁸ m/s

Time = 1 yr

= 365 days

= 365 × 24 hr

= 365 × 24 × 60 × 60 sec

Putting these values in the above formula, we get :-

$\sf{1\ LY\ Distance=(3\times10^8)\times(365\times24\times60\times60)}$

$\sf{\longmapsto 1\ LY=9.46\times10^{15}\ m}$

$\sf{\longmapsto 1\ m=\dfrac{1}{9.46\times10^{15}}\ LY }$

$\sf{\longmapsto 1\ m=1.06\times10^{-16}\ LY}$

Therefore, 1 meter = 1.06 × 10⁻¹⁶ LY.
