Violet light has a frequency of 7.26 × 1014 hz and travels at a speed of 3.00 × 108 m/s.

what is the wavelength of violet light, rounded to the nearest nanometer?

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
