What is the direction of oblique projectile at highest point?

Horizontal


All of the solar energy intercepted by the earth arrives as oblique rays?

Oblique.


What is oblique incidence?

When light is incident obliquely on an interface, its s(TE) component is reflected differently from its p (TM) component. The situation is illustrated in Fig.4.


If a dark field condenser causes all light rays to bypass the objective where does the light come from that makes an object visible in a dark field?

Oblique rays that strike the object. Oblique rays strike the object being viewed, illuminating the object and reflect light rays up through the objective.


What is meant by oblique shock wave?

For compressible flows with little or small flow turning, the flow process is reversibleand theentropyis constant. The change in flow properties are then given by theisentropic relations. But when an object moves faster than the speed of sound, and there is an abrupt decrease in the flow area,shock wavesare generated in the flow.If the shock wave is perpendicular to the flow direction, it is called anormal shock. There are equations which describe the change in the flow variables. The equations are derived from the conservation ofmass,momentum, andenergy. Depending on the shape of the object and the speed of the flow, the shock wave may be inclined to the flow direction. When a shock wave is inclined to the flow direction it is called anobliqueshock.HOE OBLIQUE SHOCKS ARE GENERATED?Oblique shocks are generated by the nose and by the leading edge of the wing and tail of a supersonic aircraft. Oblique shocks are also generated at the trailing edges of the aircraft as the flow is brought back to free stream conditions. Oblique shocks also occur downstream of anozzleif the expanded pressure is different from free stream conditions. In high speedinlets, oblique shocks are used to compress the air going into the engine. The air pressure is increased without using any rotating machinery.
