Star A is 10,000 times brighter than Star B. The exact wavelength of the spectral lines of a gas cloud are determined by the energy levels of the electrons within the gas cloud. 1 reducing the phosphor output image to the size of the active area of the CCD. Clinical applications for CCDs include all of the following except: More pixels can mean more detail, but the size of the sensor is crucial for this to hold true: this is essentially because smaller pixels are less efficient than larger ones. How does pressure affect the melting point of rock? and C2=6.00FC_2=6.00 \mu \mathrm{F}C2=6.00F. How many times farther away is Star A than Star B? This system means that each pixel only receives colour information for either red, green or blue as such, the values for the other two colours has to be guessed by a process known as demosaicing.

Two well-known graphics programs are Adobe Photoshop and Adobe Illustrator . 4 It stores light and converts it from an analog to a digital signal. 1. the x-ray photons are converted into light. In fact, those around the peripheries are typically shielded from light, which allows the camera to see how much dark current builds up during an exposure when there is no illumination this is one of the causes of noise in images. pixels.

When the size of a display is increased, its fabrication cost increases dramatically because the number of fabrication defects increases in proportion to the surface area. What is the temperature of a star (in Kelvin) if its peak wavelength is 150 nm (that is, 150 x 10^-9 m)? This can be calculated as follows 400 mm/32 pixels = 12.5mm or 1.25 cm/pixel This means that each pixel represents 1.25 cm in size If a photon deficient area is 3.0 cm in size then hypothetically you should be able to resolve it since your pixel size is smaller than the area deficient of counts 3 Structured phosphors produce more light spread. 3 It converts x-ray photons to light and stores it. 0.0430 & 1.81 \\ How many times hotter is Star A than Star B?

Question 5 1 / 1 pts Each pixel acts kind of like a . Noise reduction technology, used in most cameras, aims to cover up any noise which has formed in the image, but this is usually only attainable by compromising its detail. Using frequency response methods, a compensator was developed, given by Gc(s)=4(s+0.15)s+0.015G_c(s)=\frac{4(s+0.15)}{s+0.015}Gc(s)=s+0.0154(s+0.15).
