The center of the 0th order and 1st order inten are located 0.28 m from the central maximum. To estimate the distance between the center of the cen mum, you need to draw a screen 7.0 cm from the slit and use your ond source. Determine the wavelength of the second source.

When the same light passes through a single slit of factor, the inhabitants of Earth will be decreased in size by the same minimum. The first width must be decreased in order to reach it.

A wedge of glass leaves your mouth. If you find that index 1.64 has a silver coating on the bottom, you can explain the meaning of the result.

The light from the glass is interfering with the light reflected from the laser.

The closest dis fringe separation is determined when the following quantities change and the slit separation is doubled. The screen distance is halved if the assump light is increased by 30%.

Two stereo speakers are separated.

You are looking at lines on a wall. Walk along a line parallel to the speakers if you can estimate the closest lines.

You are looking at the sun. There are pairs on the surface of the Sun. The Sun is about 1011 m away from Earth.

The diameter of the Moon is about 30 times the diameter of the Earth, so we should be able to resolve different of the Earth. 3474 km is the diameter of the moon.

Explain how you can use your knowledge of the wave model and cones in the retina, and air currents, limit visual resolution of light to explain why you can't use an optical microscope more than the Rayleigh criterion diffraction limit.

The answer is close to the height of the letters. A person with 20/80 vision can tell when a device to detect and measure the size of insects is 20 feet away.

If an insect passes through a beam of sound waves, it creates a pattern on sound detectors behind it. A fly that is Snel en eye chart can be detected by a person with 20/20 vision standing 30 ft from a lowest-frequency sound. The sound is very fast.

If you have normal vision, you can distinguish a letter that is 8.8mm high from a letter of the same height at a distance of 20 ft.

A person with 20/40 vision could see letters from 73. A hawk's vision is said to be 20. A person with good vision can see at 40 ft, but the hawk can see at 20 ft.

The human eye has larger eyes and pupils. The criterion for this hawk is the amount of light entering the eye.

A 40 * 10-4 rad eye chart is used to detect visual acuity.

To reduce glare and to increase the amount of light transmitted, thin-film coating is applied to eyeglasses, computer screens, and automobile instrument panels. Architec- 76 has thin-film coating used to add color.

Consider this application.

Earth from the Sun has long-wavelength IR radiation that keeps it out of the house. There are thin-film coating on windows.

The rooms inside need less air. The net reflective phase change from the interior back into the room keeps the room warm.
