<span>he Dawes limit says that the resolving power is 11.6 / d, where d is your eye's pupil's diameter in centimeters. You're eye's pupil can dialate to about 7 mm, or 0.7 cm. So 11.6 / .7 = 16.5 arc seconds, or about a quarter arc minute. However, the standard answer for what people can really see is about 1 arc minute. It's linear, so 10000 / 7 = 1428 times better for the 10 meter scope. However, unless the scope is in space, the atmosphere will take a big chunk from that.</span>
Answer:
Wavelength = 0.7083 meters
Explanation:
Given the following data;
Speed of wave = 340 m/s
Frequency = 480 Hz
To find how long is the sound wave, we would determine its wavelength;
Mathematically, the wavelength of a waveform is given by the formula;
Wavelength = velocity/frequency
Wavelength = 340/480
Wavelength = 0.7083 meters
Answer:
E) microwave, infrared, visible, ultraviolet
Explanation:
Electromagnetic waves are waves consisting of oscillations of electric and magnetic fields. These fields oscillate in a direction perpendicular to the direction of propagation of the wave, so they are called transverse waves. Electromagnetic waves are the only waves that can travel in a vacuum, since they don't need a medium to propagate.
Electromagnetic waves are classified into 7 different types, according to their different frequency. In order from lowest to highest frequency, we have:
Radio waves
Microwaves
Infrared
Visible light
Ultraviolet
X-rays
Gamma rays
Moreover, for an electromagnetic wave the energy carried is proportional to its frequency:
where h is the Planck constant and f is the frequency. Therefore, the list written above also corresponds to the list of waves from lowest to highest energy. so, the correct answer is
E) microwave, infrared, visible, ultraviolet
