The critical angle refers to an angle of incidence that produces a corresponding emerging ray that has an angle of refraction of 90°. It is the largest possible angle of incidence that doesn’t result in total internal reflection. In this activity, it was estimated to be 43°.
Also, the angles of incidence and the angles of refraction were not directly proportional in contrary to the sin of the incident and refraction angles. Moreover, the observations and graph shows that the ratio sin i / sin R is a constant for any given medium and that although the incident and refracted ray appeared on opposite sides of the normal, but they all lie in the same plane.
The sine of the angle of incidence is equal to the sine of the angle of refraction multipli ed by 1.4797
Directed a single ray of light from the raybox to the centre of the curved side at an angle of incidence of about 0˚. Marked the location of the incident and emergent ray.
READ: Judaism: Questions and Answers. The conditions for total internal reflection to occur are: i. Light must be travelling in the more refractive medium. ii. The angle of incidence in the more refractive medium must be larger than the critical angle.
This laboratory was designed to investigate the behaviour of light as it travels through a denser into a less dense medium.
By doing this experiment it can be proved that there are special cases when light travels to different mediums (high to low density). When the angle of incidence is greater than the critical angle, light doesn’t follow Snell’s Law. Instead of refracting, the ray of light reflects. Apart from this difference in refraction, Snell’s Laws is followed throughout.
The objective of this experiment is to verify the validity of Newton's second law, which states that the net force acting on an object is directly proportional to its acceleration. Eq. (9)
The first law seems to be at odds with our everyday experience. Newton's first law states that any object at rest that is not acted upon by outside forces will remain at rest , and that any object in motion not ...
Since the force of friction is opposite to the direction of travel, this acceleration causes the object to slow its forward motion, and eventually stop. The purpose of this laboratory exercise is to verify Newton's second law.
Since the force of friction is in the opposite direction to the direction of motion, this acceleration causes the object to slow its forward motion, and eventually stop. Notice that Eq. (1) and Eq. (2) are written in vector form. This means that Newton's second law holds true in all directions.
are written in vector form. This means that Newton's second law holds true in all directions. You can always break up the forces and the resultant acceleration into their respective components in the. x. , y. , and. z. directions.

was derived on the basis of this law. Therefore we can consider Eq. (9) to be a prediction of the second law. In this experiment we will seek to verify this specific prediction and thereby provide evidence for the validity of the second law.
It is possible that the 1st S-wave reached the recording station before the 2nd S-wave because the 1st S-wave travels through the mantle (since the Mantle is denser the waves travel faster through that medium).
