Question

Chapter 20, Problem 1VSC

To determine

The technique used to measure the distance of the object which are at a distance of 10 million light-years.

Expert Solution & Answer

Answer to Problem 1VSC

Solution:

Cepheid variable stars technique is used to measure a distance of 10 million light-years.

Explanation of Solution

Introduction:

Effective technique is used to measure a large distance between astronomical objects.

Cepheid variables stars are extremely luminous and can be observed and measured at a large distance. There is a definite relation between the period and luminosity of Cepheid variables. With the help of period-luminosity relation large distance such as between galaxies can be found.

Conclusion:

Cepheid variables stars radiates pulses. On the bases of luminosity of cephids we can measure distance between object which are at a distance of 10 million light-years.
