A conductor loop carrying a current in a uniform magnetic field experiences a torque. This torque is determined as a function of the area, of the number of turns, the current in the conductor loop and of the strength of the external magnetic field. The torque is measured using:

In a Michelson interferometer, light is split up into two beams by a halfsilvered glass plate (amplitude splitting), reflected by two mirrors, and passed again through the glass plate to produce interference phenomena behind it in a screen. Which of the following sentences correctly describes a half-silvered glass plate action?

At Syene (now Aswan), located 800 km southeast of Alexandria in Egypt, the Sun's rays fall vertically at noon at the summer solstice. Eratosthenes, who was a Greek mathematician, geographer and astronomer (born in 276 BC) noted that at Alexandria, at the same date and time, sunlight fell at an angle of about 7° from the vertical. He assumed the Sun's distance to be very great. Given the distance between the two cities, he was able to calculate:

Oil-drop experiment was the first direct measurement of the electric charge of a single electron and was performed by Robert A. Millikan. Using a perfume atomizer, he sprayed tiny drops of oil into a transparent chamber. Each droplet picked up a slight charge of static electricity as it traveled through the air between the plates of a charged capacitor. The speed of its motion could be controlled by altering the voltage on the plates. The capacitor is charged by:

We have heard a television meteorologist talk about the dew point and the relative humidity. All air has some moisture in it, but how wet the air feels depends on the amount of moisture and the temperature of the air. It is measured using a:

The White light is obtained by additive color mixing. The overlapping projection of the primary color lights combine to form the color white. Primary color lights are:
