What Did Astronauts Service Hubble In 2009? Between 1993 and 2009, astronauts visited Hubble five times to replace limited-life items such as batteries, gyroscopes and electronic boxes, and to install state-of-the-art science instruments. Each time astronauts visited Hubble, they left it a more capable, more productive observatory. When was Hubble serviced? Date: May 11-24, 2009.
What Is Angle Of Incidence And Refraction? The angle that the incident ray makes with the normal line is referred to as the angle of incidence. Similarly, the angle that the refracted ray makes with the normal line is referred to as the angle of refraction. What is the angle or refraction? : the angle
What Is The Bending Of Light By A Lens Called? Light travels in waves and when it passes through media with a different density than air, such as water, the light changes direction, or bends. This is why a pencil looks bent when it is halfway submerged in a glass of water. This bending of
What Is Critical Angle With Diagram? Include a ray diagram to explain the concept. The critical angle occurs when the angle of incidence where the angle of refraction is (text{90})(text{°}). The light must travel from an optically more dense medium to an optically less dense medium. What is critical angle explain with an example? So
What Is Refractive Index And Write Its Formula? The refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n
What Are The Two Formulas For Refractive Index? Refractive index is also equal to the velocity of light What is refractive index and write its formula? The refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the
Why Can Virtual Images Be Projected On A Screen? Virtual images cannot be obtained on the screen because the image formed is from the light rays that do not meet but appear to meet when they are produced backwards. The image obtained will always be erect. Why can a real image be projected on a
