Newton's Corpuscular Theory:
Newton's corpuscular theory of light states that
1. Light is emitted form of tiny particles is known as corpuscles.
2. The corpuscles travel with the velocity of light.
3. When corpuscles strike the surface they caused to sensation of light.
4.Medium is essential for propagation of light.
5. Velocity is greater in denser medium as compared to rare medium.
6. The velocity of light depends upon the temperature of the body emitting the light.
Q. The colour codes of a carbon resistor are yellow, yellow, orange. Tolerance is 5%. Find the resistance. The initial yellow ring corresponds to 4. The subsequent yellow ring
what is space charge and diffusin capacitance.
Q. When there is no feedback, the gain of the amplifier is 100. If 5% of the output voltage is fed back into the input through a negative network, find the voltage gain after feedb
QUESTION 1 A car of mass 800 kg is pulling a trailer of mass 300 kg up the slope of angle ? to the horizontal where sine ? = 1/200. Resistance to motion (apart from gravity) is 1.
what are characteristics of resistances
A transformer has 1200 primary turns and 200 secondary turns. The primary and secondary resistances are 0.2Ω and 0.02Ω respectively and the corresponding leakage reactances a
Radiation and Radioactivity Investigator of radioactivity discovered that certain natural elements, primarily the very heavy ones, have unstable nuclei that disintegrate to emi
1. What do you understand by diffraction of waves? Explain why the diffraction of sound is more easily observable than the diffraction of light? 2. The wavelength of two spectra
The velocity with which the group of waves travels is called as group velocity or the velocity with which a ray packet goes is called as group velocity
Q Calculate the longest wavelength that can be analysed by a rock salt crystal of spacing d = 2.82 Ao in the first order. Data: d = 2.82 Å = 2.82 × 10-10 m; n = 1 ; λmax = ?
