Refracting telescopes, if uncorrected, suffer from chromatic aberration.
Chromatic aberration occurs because:
a) red light is focused more strongly than blue light
b) blue light is focused more strongly than red light
c) the outer light rays are focused more strongly than the central rays,
d) the central light rays are focused more strongly than the outer rays.
Ans- Blue light is focused more strongly than red light
What is the difference between the Atomic Theory and the Kinetic Theory? Atomic theory is all about structure of an atom, i.e., its composition. Like an atom in general is made
what is friction force? why does opposes the motion?
Ionisation: If the amount of external energy is large enough the valence electron can gain sufficient kinetic energy (energy of movement) to be removed completely from its atom
Explain Newton Second Law - Linear Motion If objects only followed Newton's first law then everything would be traveling in straight lines at a constant velocity or at rest. B
Define the Nuclear Power As an energy source, nuclear power is an alternative to fossil fuels. Controlled nuclear chain reactions are used to generate electricity in a safe ma
What is a Temperature Scales? Fahrenheit, Celsius and Kelvin were scientists who studied how heat and temperature work. The most familiar scale to Americans (until the time tha
A 2350-kg granite tombstone absorbs 2.8 x 10 7 J of energy from the Sun to change its temperature from 5.0°C at night to 20.0°C during an autumn day. Verify the specific heat
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) Momentum but not energy b) Neither momentu
A ray of light travelling in air is incident on a prism and passes through it with a speed of 2X10 8 ms -1 parallel to its base. If the angle of refraction is similar to half of
Explain Circular and Orbital Motion Let's start by looking at circular motion with constant speed. Can there be acceleration in this problem? Yes, velocity includes speed and
