The emitted light tends to be monochromatic (one color) that depends on the band gap (and other factors). The color of the light emitted by LED depends on Current flowing into base of transistor is 100microA and current gain is 100 then its collector current will be In … Older Post, Post Comments 0 (D). The color the LED emits, thus, depends on the wavelength of the photons emitted from recombination. खाद्य ऊर्जा को हम किस इकाई में माप सकते हैं ? The color of the light emitted by LED depends on, The color of the light emitted by LED depends on, The base of the transistor has a thickness of, The two inputs A and B of NAND gate has 0 output if, The gain of non inverting amplifier is given by G =, If 3.5V is applied to a gate it will accept it as, The gate whose output is 0 only when the inputs are different is called, Gate that is also known as inverter is called, Open loop gain of an amplifier can be represented by the formula, One that is based on forward biased PN junction is, Current flowing into base of transistor is 100microA and current gain is 100 then its collector current will be, The gate having output 1 only when one of its input is 1 is called, In op-amp the signal applied at inverting terminal appears at the output terminal with a phase, The ratio of the forward voltage and a forward current is known as, The diode characteristic curve is a plot between, In a PNP transistor the n-region as compared to the p-region is, In reverse biased situation a very small current flows due to, In half wave rectification , during the negative cycle of the wave the diode is, In a half rectification the diode conducts during, When the semiconductor is doped half with trivalent and half with pentavalent impurities then the junction formed is known as, Function of photovoltic cell is reverse of, A transistor can be used as a switch ON if Vce is nearly. किसे लोकसभा की कार्यवाहियों में भाग लेने का अधिकार तो है, परन्तु मत देने का नहीं है ? The colour of emitted light from LED depends on. प्रसिध्द खजुराहो मंदिर का निर्माण किसने किया था ? ), ( When an electron moves from a high-energy orbit to a lower-energy one, it emits energy in the form of light. The voltage across the LED corresponds to the value of the band gap energy. A. The color of the emitted light depends on the energy difference between the old orbit and the new one. The light color emitted by the GaP x As 1-x diodes is indicative of the magnitude of energy needed for an electron to cross the band gap. महान लॉन टेनिस खिलाड़ी बोर्न बॉर्ग किस देश का है ? laminar flow (B). Log in. This effect is a form of electroluminescence. Colors can be categorized into the following groups depending upon the effect they have on us. The colour of the light emitted in LED is determined by the semiconductor materials that form the diode’s PN junction. The graphene-based LED’s color depends on the applied voltage. The color always is dependent upon the light's frequency, which is the number of waves of the light that pass a given plane in space per second (that is, the number of cycles per second). its forward bias (B). सूर्य में कौनसी गैस सर्वाधिक पाई जाती है ? The shape, or width, of the emitted light beam is determined by a variety of factors: the shape of the reflector cup, the size of the LED chip, the shape of the epoxy lens and the distance between the LED chip and the epoxy lens. A1v2 2v2 (C). Plant growth and development depend on the availability of light. Answer. no light (D). This process, called electroluminescence, is illustrated in Figure 3–29.
