A polarizer selectively transmits light waves oscillating in a specific direction while blocking others. When randomly polarized light (which contains waves vibrating in all directions perpendicular to propagation) passes through a linear polarizer, only the component aligned with the polarizer's transmission axis passes through. The emerging light becomes plane-polarized, meaning all waves vibrate in the same direction. It is not partially polarized (which implies some randomness remains), blocked (which would mean no transmission), or unchanged.

Dharam Singh served as the Chief Minister of Karnataka from 2004 to 2006. S.M. Krishna preceded him. This question is time-sensitive and refers to the political situation in 2004.

Jennifer Hawkins from Australia won the Miss Universe 2004 pageant held in Quito, Ecuador. Shandi Finnessey was Miss USA 2004 (and placed first runner-up at Miss Universe). Alba Reyes was Miss Puerto Rico and a finalist. The winner of Miss Universe 2004 was indeed Jennifer Hawkins, making option A correct.

Chris Cairns (New Zealand) holds the record for the most sixes in Test cricket with 87 sixes. While Viv Richards was known for aggressive batting and Sachin Tendulkar is the leading run-scorer, Cairns specifically holds the six-hitting record in Test matches. Wasim Akram, though a great all-rounder, doesn't hold this particular record. The record is specific to Test cricket, not ODIs or T20s.

Venus transited the Sun on June 8, 2004, after a gap of 122 years (the previous transit was in 1882). Venus transits occur in pairs separated by 8 years, with over a century between pairs. Mars, Jupiter, and Saturn cannot transit the Sun as viewed from Earth because their orbits are outside Earth's orbit around the Sun. Only Mercury and Venus can transit the Sun from our perspective.

FIFA (Fédération Internationale de Football Association), the world governing body of football/soccer, celebrated its 100-year anniversary in 2004. Founded in 1904, FIFA marked its centenary in 2004. Hockey's FIH was founded in 1924, the International Badminton Federation (now BWF) in 1934, and the ICC (cricket) in 1909 - none of these celebrated 100 years in 2004.

Justice R. C. Lahoti served as the Chief Justice of India from 2004-2005, succeeding Justice V. N. Khare. Justice Rajendra Babu was a Supreme Court judge but not Chief Justice in this context. The question refers to the appointment in 2004, when Justice Lahoti took office. The note that this is dated content (current as of mid-2000s) is important as the position has changed many times since then.

Light waves are transverse waves, meaning the oscillations of the electric and magnetic fields are perpendicular to the direction of wave propagation. Unlike longitudinal waves (like sound) where oscillations are parallel to propagation, light's transverse nature is why it can be polarized. Longitudinal waves cannot be polarized.
