WebGravitational Fields Structured Questions. Q3. (a) (i) Explain what is meant by the gravitational field strength at a point in a gravitational field. The gravitational field strength at a point is the force per unit mass acting on a small test mass placed at that point in the field. WebThe shift in the wavelength is given by a simple formula (λo - λR) / λR = v/c Where λR = Rest wavelength λo = Observed wavelength v = velocity c = speed of light so long as the velocity v is much less than the speed of light. A relativistic doppler formula is required when velocity is comparable to the speed of light. texas republic bank celina tx
